CHAPTER NINE

After dumping their bags Sherlock and Matty headed down the hotel’s staircase and out into the town. The sun had dropped beneath the horizon, and the darkness of the night was leavened by gas lamps and by flaming torches attached to brackets on the stone buildings. People were already thronging the streets, crossing from one tavern to another apparently in search of a better time than they were already having. Avoiding all of the activity as far as they could, the two of them found a relatively civilized tavern where they could sit in a corner and eat a gammon pie each, washed down with a watery beer which the barman seemed to have no problem serving them. However, when Sherlock asked for a pitcher of water the man just looked at him with a scowl on his face.

Every few minutes a different person tried to sit down beside them and engage them in conversation. Sometimes it was a woman with more make-up than was necessary and wearing clothes that looked as if they hadn’t been washed in a while, but more often it was an unshaven man in a stained suit or a grey collarless shirt and braces. Matty always said the same thing – ‘Our dad will be here in a minute, and he wouldn’t like it if he found you here’ – and they quickly left with a muttered apology or a curse. The first time it happened Sherlock just shrugged it off, but after the third time he stared at Matty with a question in his eyes. Matty avoided his gaze. ‘There’s some strange people around,’ he muttered. ‘Don’t matter what town you’re in, they always try and make friends with you if you’re a kid alone. You learn early on not to have anything to do with them.’

Sherlock didn’t ask any questions. It was obvious that Matty didn’t want to go into details, but once again he was glad to have his friend with him.

For a while they discussed what to do about Rufus Stone. It was clear that they had both secretly hoped that they would find him, or at least a message from him, at the hotel. The fact that there was nothing had rattled them more than they wanted to admit.

‘We could go to the police,’ Matty suggested. ‘Tell them that he’s gone missing.’

‘The trouble is that we don’t actually know what has happened to him, so there’s not much the police can do. It’s not like we saw him being abducted. They’ll say he just missed the train and he’ll turn up tomorrow. Worse than that: they’ll worry about two kids alone in Edinburgh. They’ll assign a guardian to us, or place us in some philanthropist’s home until Rufus arrives. That’s the last thing we want.’

Matty nodded. ‘I can see that. What about your brother, though? We could send him a telegram, tell him what’s happened.’

‘And within an hour he’ll send a telegram back telling us that we have to return to London until he knows what’s happened to Rufus. If he does that, then I won’t be able to disobey him – I’ve tried that before, and it never works out well. No, we need to be here. It’s best that we don’t tell anyone what’s happened.’

‘What do you think’s happening to Rufus?’ Matty asked quietly, not looking at Sherlock.

Sherlock sighed. He’d been trying not to think too hard about that. ‘I don’t know for sure. Maybe those two Americans have taken him, and they’re asking him what he knows. Given that he doesn’t know anything that they don’t already know, they’ll probably release him.’ Or kill him, Sherlock thought, but he didn’t put his fear into words. Although Matty was streetwise in a way that Sherlock would never be, he was younger than Sherlock, and there were some things he needed protecting from.

‘He knows about Edinburgh,’ Matty pointed out.

‘If they were on the train with us, then they know about Edinburgh as well. That secret is out of the bag, I suspect.’ He paused for a moment. ‘On the other hand, if it’s the Paradol Chamber, then I don’t know what they want with him.’

Sherlock found that the conversation had blunted the sharp edge of his appetite. Thinking of what might be happening to Rufus while they were relaxing in a warm bar and eating well made his stomach lurch.

‘I don’t want to worry you,’ Matty whispered after a while, ‘but have you seen the bloke over there?’ He nodded his head at the opposite wall. ‘In the booth, sitting by himself.’

Sherlock glanced over, trying not to be too obvious about it. He was worried that Matty might have spotted Mr Kyte, but when he saw the unfamiliar thin man sitting alone in the booth he breathed a sigh of relief. A moment more and he started to feel uneasy, however. The man didn’t show any signs of being interested in the two of them, but there was something odd about him, something Sherlock couldn’t quite work out. He was painfully thin, for a start, as if he’d been starved for weeks, and his skin was so white it was almost translucent. His eyes seemed invisible in the dark shadows of his eye sockets, and the bones of his cheeks and his chin pushed out against the tautness of his face so much that Sherlock thought the skin might suddenly split as he watched. There was something strange about the man’s clothes as well: they looked like they might have been his Sunday best, but they were coated in dirt, and there was a green tinge to his shoulders and sleeves. He was staring straight ahead, but he didn’t appear to be looking at anything in particular. Nobody was sitting near him, and although he didn’t have a drink in front of him, the barman didn’t seem to want to go across and either take an order or throw him out. The man just sat there doing nothing.

The crowd in the tavern grew larger, and eventually the view of the strange pale-skinned man was blocked by people. Sherlock and Matty finished eating their pies and got ready to leave. As they stood up a gap opened in the crowd. Sherlock looked across. The man had gone.

‘You ever heard of the Resurrectionists?’ Matty asked as they left the tavern. He seemed edgy.

‘I don’t recognize the name,’ Sherlock said.

‘It was two blokes named Burke an’ Hare. Both called William. They was notorious up in this neck of the woods a few years back. I heard about them when me dad was up here, working. Lookin’ at that bloke back there reminded me of ’em. Edinburgh is one of the places doctors come to train, cos of the Edinburgh Medical College, but they’ve got a problem: how do they find out about the ’uman body if they can’t examine ’em, cut ’em up, like, when they’re dead – see where all the organs is, an’ where the blood goes?’

‘I thought medical schools were allowed to use the bodies of executed criminals,’ Sherlock said, frowning.

‘In theory, yeah,’ Matty responded, ‘but there’s always less bodies available than there’s student doctors wantin’ to take a look at ’em. An’ the number of things you can be hanged for has gone down a lot, which means there’s a lot less bodies available for use. Sixty years ago there was over two ’undred different crimes that led to an ’anging. Now there’s only five. So only about two bodies a year came up for use by the College. Which is where Burke an’ Hare came in.’

‘I have a feeling I know where this is going,’ Sherlock said quietly, feeling a shiver down his spine. ‘They dug up corpses and sold them, didn’t they?’

Matty stared at him. ‘Not quite,’ he said, ‘although a lot of that did go on. “Bodysnatching”, it was called. There was so much of it happening that friends and relatives of anyone who had just died used to keep watch over the grave to stop it being dug up. Some people – rich people – used to have cages built around graves of their relatives to stop anyone getting in. Before they realized what was going on, people used to visit the graves of their loved ones and find them disturbed, as if the bodies had come back to life an’ just crawled out of their own accord.’ He and Sherlock were pushing their way through the crowded streets towards their hotel. ‘Course, once people got to know about the bodysnatchers, they had to change how they went about things. They was quite inventive, the bodysnatchers. They used wooden spades, cos they made less noise than metal ones, an’ they used to dig down at an angle, so that any disturbance to the grave would be a way away, not directly over it. They’d uncover the end of the coffin, smash it open an’ drag the body out with a rope.’

‘All right, but you said this Burke and Hare weren’t bodysnatchers. What were they then?’

‘They was both Irish, for a start,’ Matty replied, ‘an’ they moved to Edinburgh to work as labourers on the Union Canal. Burke ended up stayin’ at a boarding ’ouse run by Hare’s missus. They got to be drinkin’ buddies, an’ they got talkin’ one night about ways of makin’ some money. One of ’em suggested that they could steal the body of someone who ’ad died locally of natural causes an’ ’ad no family, like, an’ sell it to someone at the College who could use it to demonstrate ’uman anatomy to students. It weren’t long before some old pensioner who owed Hare four quid died of natural causes. Burke an’ Hare made sure the coffin that was buried was filled with tree bark, ’an they flogged the body to a Dr Knox ’ere in the city for seven quid.’

‘Very enterprising,’ Sherlock said drily.

‘Problem was that people weren’t dyin’ of natural causes fast enough for ’em, so they decided to ’elp ’em along a bit. First one they actually killed was a local miller. They got ’im drunk on whisky an’ then suffocated ’im. Second one was another pensioner, a woman this time, named Abigail Simpson. After that . . .’ He shrugged.

‘Well, they was off an’ runnin’. Dr Knox would pay ’em a guaranteed sum for every dead body they delivered to ’im, no questions asked – ten quid if the body was in good nick, eight if there was anything wrong with it. They preferred women and kids, of course, cos they was easier to subdue an’ to suffocate.’

Sherlock found he was feeling sick. It was the casual nature of what Burke and Hare had done that offended him. The murders weren’t crimes of passion, or ‘spur of the moment’ incidents – they were a series of what were effectively business decisions. Business decisions that left people dead.

‘How many people did they end up killing?’ he asked quietly as they turned the corner and headed towards the hotel’s front door.

‘Best guess is seventeen,’ Matty answered, ‘over the course of a year.’

‘And didn’t anyone suspect? I mean, the doctor they were selling the bodies to must have realized that they weren’t executed criminals. Hanging must leave a distinct mark on the neck, and those corpses wouldn’t have had that mark.’

‘Dr Knox? Yeah, he knew, all right, although Burke later swore otherwise. He just didn’t want to disrupt the supply of bodies. He was getting a reputation as being the best anatomy teacher around, an’ students were flocking to his lectures, and payin’ for the privilege. He wasn’t going to give all that up.’ He snorted. ‘Story is that there was one bloke that Burke and Hare killed, name of Daft Jamie, who was well known around the town. When Dr Knox uncovered the body in the lecture theatre, ready to cut into it, some of the students recognized it. Knox said that it must be someone else, but he started the dissection on the face first, to make it unrecognizable quickly.’

‘What happened in the end?’ Sherlock asked, as he pushed open the front door. ‘I presume they were found out, otherwise you wouldn’t know all this.’

‘Burke and Hare killed a woman in their lodging house named Marjory Docherty, but until they could get rid of the body they hid it under a bed. There was lodgers there, an’ they got suspicious. When Burke was out of the way they checked his room, an’ they found her. So they called the peelers. Burke and Hare got the body out of the house before the peelers turned up, but they took it to Dr Knox’s place, where the peelers found it later. Hare turned Queen’s evidence and testified against Burke in exchange for immunity from prosecution. Burke was hanged, an’ his body was publicly dissected at the Edinburgh Medical College – perfectly legally, of course.’

‘And what happened to Hare?’

‘Vanished. Never heard of again.’

‘So he might still be here, in the city?’

Matty nodded as he opened his bedroom door. ‘Might well be, although it’s more likely that he went back to Ireland.’

The next morning there was still no word from Rufus Stone. Disconsolate, Sherlock and Matty ate a breakfast of oat porridge served by a silent maid. It was so thick that Sherlock could have cut it into slices with a knife, and it looked like pigswill, but it was surprisingly tasty, and filling as well.

‘What’s the plan?’ Matty asked.

‘I’m going to find a bookshop or a library,’ Sherlock replied. ‘I need a map of the city, and I need to find out more about the place. I feel lost here. I can’t find my bearings. Why don’t you go and check the places you used to know, see if there’s anyone who remembers you and can help us. We’re going to need all the help we can get.’ He paused for a second, thinking. ‘That park, up the street from the hotel – let’s meet just inside the front gates at midday.’

‘I ain’t got a watch,’ Matty pointed out.

‘Then ask someone.’

Having finished their porridge, they said their goodbyes and went out into the street.

Sherlock found a library a little way along the main thoroughfare. Inside, the dry smell of the books was comforting. It reminded him of Uncle Sherrinford’s library. He always felt at home with books. Moving to the section devoted to Scotland, he pulled an armful of volumes off the shelf and settled at a nearby table to read.

Within an hour he had a much better idea of the geography and the history of Edinburgh, and its place within the wider history of Scotland. The town was built on seven hills, he discovered, which he supposed would explain the fact that every direction seemed to be either uphill or down.

After a while the close black print started blurring as he tried to read it. He closed the book and shut his eyes for a moment. The problem was, he thought, that the kind of information he wanted wasn’t the kind that went in reference books. Where did people go in Edinburgh when they were on the run? How did they avoid detection when someone was looking for them? Who was in charge of the local criminal fraternity, and were they more likely to help a person on the run or the people chasing them?These were the kind of things that Matty was more likely to find out from his contacts, but unless it was written down and kept up to date then it was the kind of information that would just slip away. Sherlock decided that he needed to write down all the little snippets and facts that he or Matty unearthed along the way. Maybe if he kept them on file cards then he could access them the next time he needed them.

A sudden, disturbing thought struck him, and he shivered. What he was proposing wasn’t that different from what Josh Harkness had done – collect information on dubious and illegal activity and keep it. The only real distinction was that Sherlock wouldn’t be using it for profit.

He checked the watch that usually hung from a chain on his waistcoat. It was half past eleven. Time to start thinking about meeting Matty.

As he returned the books to their shelves he noticed that there were maps of Edinburgh for sale at the front desk for sixpence. He bought one and took it back to the table where he had been reading to open it. His gaze scanned quickly across the details: the shape of the city and in which directions the main roads ran. He located the main railway line coming in from London, and traced the route the cab had taken. It had gone along a road named Princes Street – clearly the main road through the city. That enabled him to work out where their hotel was, and where he was now.

Folding the map up and putting it in his pocket, he set off for the park. He felt more confident that he could navigate his way around now.

The sun was shining through the clouds, casting beams of light diagonally across the mottled blue and grey as if girders of light were holding up the entire sky. Glancing down side roads as he strolled along Princes Street he caught glimpses of the castle. It no longer looked like a solid grey cloud hanging above the city, but there was something about it that defied geometry and perspective. It looked as if it just shouldn’t be possible that the castle was up there while the town was down here.

As he passed one particular alley, something in the shadows made a scuffling noise. He stopped, intrigued, and looked sideways. He made no move to get any closer to the alley – that would have been stupid – but if anyone was following him then he wanted to know who it was.

For a moment he could only see a pool of shadow, like liquid darkness, where the sun could never penetrate, but after a few moments his eyes got used to the contrast and he could make out something that seemed to be floating in mid-air, like a pale balloon. It took a moment of concentration before his brain realized what he was looking at – the face of someone dressed entirely in black who was standing there, in the alley, staring out.

Sherlock took an involuntary step backwards. The face was bone-white, with eyes set so deep that the sockets were just black holes in the face. The cheekbones stuck out sharply, and the lips – if the figure had any lips – were pulled back from teeth that seemed to grin at Sherlock as if the figure was enjoying some private joke. For a long moment Sherlock was convinced that a rotting human body, something close to a skeleton, was standing there, in the alley, looking at him. Had it been ripped from the ground and left there, propped up against a piece of wood, as a warning? And who would do such a macabre thing?

The figure raised a hand to the side of its face and waved, then drew back into the darkness until Sherlock couldn’t see it any more. Only after it had gone, leaving him cold and shaking, did he remember the man in the tavern, the one who had been sitting alone. Had it been him?This figure had looked even more skeletal, even less alive, but that might have been a trick of the poor light.

What was going on? He thought back to what his aunt and uncle had told him. Was he going mad, like his father?

For a few seconds Sherlock wanted to go further into the alley, looking for the figure – looking for the truth about what he’d seen – but he pulled back. Logically, the most likely explanation was that this was a trap, and the figure was bait to lure him in. But was it random, or did someone know that his curiosity often outweighed his good sense? Rattled, Sherlock walked away from the mouth of the alley and he didn’t look back.

The park was only a few minutes further. When he got there, Matty was already waiting.

‘Are you all right?’ his friend asked. ‘You look like you’ve seen a ghost.’

‘Don’t be stupid,’ Sherlock replied sharply. ‘There’s no such thing as ghosts.’

‘All right – keep your hair on.’

‘Did you find anything out?’ Sherlock asked.

Matty shook his head. ‘Most of the blokes and kids I knew around here have moved on. That or they’ve died. I did find a couple of people who remembered me, but they don’t know anything about a big American who’s come through this way. What about you?’

‘I could find my way around the city now.’

‘Well, I suppose that’s something,’ Matty said critically. ‘If we was ever planning on moving here.’

‘Don’t underestimate the usefulness of geographical knowledge.’

Matty stared at him. ‘So what’s our next move?’ he asked eventually.

Sherlock pondered for a moment. He’d been debating this question himself. ‘I suppose we could go back and talk to the ticket collectors and the guards at the station here,’ he said slowly, ‘but they must see hundreds of passengers a day, and there’s no guarantee that they would remember Mr Crowe. Besides, if he continued to be as careful as he was back in Farnham, then he would have got off at an earlier station and maybe hired a cart to bring him and Virginia to Edinburgh.’

‘If he’s here at all,’ Matty pointed out. ‘After all, you’ve only got a dead rabbit’s head pointing you here. It’s not much to go on. I still reckon we might have gone off in completely the wrong direction.’

‘Despite Rufus vanishing?’ Sherlock asked.

Matty shrugged. ‘You’ve got a point. The clue was probably a good one, but now that it’s got us here, what do we do? Wait for another one to come along?’

‘Matty,’ Sherlock said slowly, ‘I’ve said it before and I’ll say it again – you may not be a genius, but you can bring out the genius in those around you.’

‘What do you mean?’

‘Amyus Crowe left a clue that would bring us to Edinburgh, if we understood it properly. Why did he do that? We’ve not asked ourselves that question yet.’

‘Because he wanted us to follow him,’ Matty replied.

‘Exactly. He wanted us to follow him. He wasn’t just saying “Goodbye – I’m off to Edinburgh!” He wanted us to know exactly where he was heading, and the only reason for that was because he wanted us to come after him. He wants our help. Now we’re here, he’s not going to leave us dangling. He’ll leave another clue around, one that will lead us right to where he is.’

‘Why couldn’t he do that from the start?’ Matty asked.

‘Because all he knew was that he and Virginia were heading to Edinburgh. Once he was here he would find somewhere to settle down in peace – somewhere he wouldn’t be detected. Not a hotel then. More likely a cottage somewhere outside the town that he could rent. Once he knew his address, he would find a way of letting us know.’

‘But he doesn’t know where we are,’ Matty pointed out.

‘So he would leave a message somewhere that we could see it no matter where in the town we ended up.’ He thought back to the newspaper that he had read on the train. In particular he remembered the page of classified advertisements that had so fascinated him: messages from one person to another, or one person to a group of people, either in plain language or in code. ‘He’ll place a classified advertisement in the local newspaper,’ he said with certainty. ‘He knows that’s one of the places I’ll look.’

‘But what if we missed it? What if he put the message in yesterday?’

Sherlock shook his head. ‘He wouldn’t know what day we were going to be here. If I know Amyus Crowe, he would pay for the advert to be in all week.’

Matty nodded. Either what Sherlock had said made perfect sense to him or he was willing to take it on trust. ‘Then let’s get a local newspaper. Let’s get all of them.’

‘How many are there?’ Sherlock asked, wondering if they were going to have to plough their way through ten or twelve newspapers, or whether Amyus Crowe would have put the advertisement in all of them.

‘Three,’ Matty said. He turned to go, then turned back. ‘You’ll have to read ’em,’ he pointed out, ‘cos I can’t read. And I ain’t got any money on me, so you’ll have to buy ’em as well.’

They found a newspaper vendor just outside the park and bought copies of all three Edinburgh newspapers for that day, then went back into the park and sat on a bench where Sherlock could read them. He couldn’t help but notice that the Edinburgh murder story – the one he’d seen in the copy of The Times on the train – was the front-page story on all three papers. The first one – the Edinburgh Herald – was representative of them all:

The Black Reavers? The name of the gang struck a chord in Sherlock’s mind. It made them sound dangerous, even sinister. He was about to move on to the classified section of the newspaper when he spotted the name again, this time in a report directly beneath the paragraphs on Sir Benedict Ventham’s poisoning:

He moved on to the classified section. It wasn’t as large as the one in The Times – barely half a page. Most of the advertisements seemed to be from households requiring a maid, a cook or a butler (‘references essential’), with a handful advertising lost property (‘Found in King’s Street, a lady’s brooch – emeralds set in gold. Prospective owners must apply in writing with full description of item before collection can be arranged’). Nothing struck him as being the kind of thing that Amyus Crowe would have written.

Just in case, he checked the letters pages as well. These mostly seemed to be complaints about factual inaccuracies in previous editions of the paper, or comments on the lack of manners of the lower classes, but one letter in particular caught his eye, and he read it out to Matty:

The letter made Sherlock think about the two skeletal figures that he’d seen – the one in the tavern the night before and the one in the street only half an hour ago. Was this what the letter was referring to? Was there a spate of people who looked like dead bodies walking the streets and, if so, what did it mean?

He pushed the thought aside. Interesting though these speculations were, they didn’t help with the immediate task – finding Amyus Crowe and Virginia, or Rufus Stone.

In the Edinburgh Star the classified adverts were skewed more towards notifications of upcoming dances (or ‘cèilidhean’, as they seemed to be known), lost pets and horses for sale. One in particular caught his attention: ‘Parakeet missing, can recite entirety of Hamlet and selected poems of Tennyson. Reward paid for return.’ A parrot that could recite the whole of Hamlet? Sherlock couldn’t believe it.

It was in the Edinburgh Tribune that he found what he was looking for. Nestled among the usual set of advertisements was one that immediately stood out.

‘That’s it,’ Sherlock said, pointing to the advertisement.

‘I can’t read,’ Matty explained patiently.

Sherlock read the advert out to Matty, who frowned. ‘Bit long-winded,’ he said, ‘and a bit creepy as well. Don’t strike me as the kind of place ordinary people stay.’

‘It’s not a real hotel,’ Sherlock said.

‘How do you know?’

Sherlock indicated the first three words. ‘The Sigerson Hotel. My father’s name is Siger – Siger Holmes. That makes me Siger’s son. The advert is aimed at me.’

Matty looked dubious. ‘Could be a coincidence. Maybe there is a Sigerson Hotel.’

‘Possible,’ Sherlock conceded, ‘but these adverts are paid for by the word. There are a lot of words here – more than you need to tell people how good your hotel is, but enough to contain a hidden message.’

‘So Mr Crowe and Virginia are in Kirkaldy Town.’ Matty scowled. ‘That’s miles away. I thought they were supposed to be in Edinburgh.’

‘The mention of Kirkaldy is a red herring. That’s not where they are.’

‘Then where are they?’

Sherlock shrugged. ‘I don’t know. I have to decode the message.’

He looked at it again. If it had been a set of random letters or numbers then he would have tried a substitution cipher, the way that Amyus Crowe had taught him. Substitution ciphers were based around the principle of substituting one thing for another – replacing every letter a with a number 1, for instance, every letter b with a 2, and so on. Decoding them, if you didn’t know what the substitution strategy was, depended on knowing the relative frequency with which particular letters occurred in normal writing. E was the most common letter, followed by t, a, i, o and n. So all you had to do was look for the most commonly occurring letter or number, and replace that with e, then work your way down the list – although you did need quite a large sample of code to break in order to have a good chance of getting it right. Scanning the message, though, Sherlock realized that it wasn’t a substitution cipher. For one, it made a strange kind of sense. It read as an advertisement. Replacing the letters of a sentence or a paragraph with other letters would result in a completely scrambled set of meaningless words. So the code had to be something else. He took a pen out of his pocket and quickly scribbled down the initial letters of the words in the margin of the newspaper, but he only got a little way – f t i p t r a r . . . – before he realized that he was on the wrong track.

Perhaps it was the last letters, he thought. He scribbled another set of letters – d e l e o t d x . . . No, that didn’t look right either.

Perhaps he should start from the end, rather than the beginning. He tried both options again – first letters and last letters – but all he got for his trouble was f i t k n u l . . . and e n n y r s e . . . Unless Amyus Crowe was deliberately confusing the issue by writing in a foreign language, Sherlock was on the wrong track.

Maybe he should be looking at words rather than letters. He tried every first word of a sentence – find tell two mr locate – then every second word – the us days and us. With the proviso that the second one sounded a bit like bad poetry, it was no good.

He sighed and bit the inside of his lip, aware that Matty was intently watching what he was doing. He was running out of ideas. Maybe this thing was too complicated for him to decipher.

Something was nagging at the back of his brain. He tried to force himself to relax, to stop thinking so that the thought could work its way to the surface. He had tried first words of sentences, and second words. What if . . . what if he tried the first word of the first sentence, the second word of the second sentence, and so on?

He knew the advertisement so well by now that he could write down the words from memory.

Find us in Cramond Town.

‘Got it!’ he whispered.

‘What?’

‘They’re in a place called Cramond,’ he said.

Matty looked dubious. ‘I thought you said Cramond was the name of the people who owned the hotel.’

‘There is no hotel,’ Sherlock explained again. ‘It’s a code. Mr Crowe had to get the name of the place in there, but he made it look like something else – a person’s name – and he then distracted attention from it by referring to a real place – Kirkaldy.’

‘All right – where is this Cramond?’

Sherlock pulled out the map he had bought from the bookshop. On the reverse side of the Edinburgh map was a map of the surrounding area. In the top right-hand corner was an index relating to a grid of letters and numbers around the edge. He scanned down the index until he found Cramond – not without a little flash of pride – and then checked the grid reference on the map. ‘It’s on the coast,’ he said. ‘Just a few miles away. We can probably get someone to take us there in a cart.’ He folded up the map and the newspaper, putting them into his pockets. He felt a sense of relief and weariness wash over him. He’d done it! He’d located Amyus and Virginia Crowe!

Now came the hard part – finding out why they had left, and persuading them to return . . .

A movement over Matty’s shoulder made him glance past his friend. Two men were approaching. One held something in his hands: it looked like an empty sack. It took a moment for Sherlock to identify him as the smallpox-scarred American he had seen in Farnham, and then again at Newcastle Station. A chill ran down his spine, and he felt his heart suddenly speed up. His eyes flickered sideways, to Matty’s face. He was just about to tell Matty to run when he noticed that the boy was staring over Sherlock’s shoulder. His eyes were wide and scared.

More men must have been coming up behind Sherlock – probably including the man with the missing ear and the ponytail. Sherlock was about to push Matty left and dive right himself when the man behind Matty realized that they’d been spotted, rushed forward and threw the sack over the boy’s head. Sherlock reached out to tear the sack away, but the world went dark as something heavy dropped over his head and covered his face. Hands grabbed him and pushed him off his feet.
