I didn’t concern myself with Abdou’s trial. I had to wait for the mobile-phone records to arrive anyway, because on the result of that inquiry depended the line I would take in my final speech. Until then it was pointless to re-read documents or prepare for the closing argument.

On Thursday afternoon Margherita called me on my mobile. I had heard nothing from her since the message on Sunday evening. I hadn’t called her, or tried her on the intercom. I don’t know why. Something had held me back.

Would I care to go out for a drink after supper? Yes, I would. Should I buzz her from down below or knock at her door? Ah, she was going out earlier and could we meet up somewhere, fairly late on. How would Via Venezia suit me? In front of the Fort at about half-past ten? Fine by me. See you later, then.

Her tone of voice was a little puzzling, and worried me slightly.

From that moment on, the afternoon dragged by. My thoughts wandered and I kept looking at my watch.

I left the office at about eight, went home, had a shower and change of clothes, and started off long before the appointed hour. I whiled away the time in one way or another, and headed towards the Fort at about ten.

I walked up the slope of Via Venezia, crowded as it always was at that hour in summertime.

Mostly with groups of youngsters. They exuded a mixture of deodorant, sun cream and mint-flavoured chewing gum. A few bronzed fifty-year-olds with twenty-year-old girls in clouds of perfume. Very few of my age. I wondered why, just to give my mind something to toy with.

I reached the Fort at least ten minutes early, but I felt better simply because time had passed. I leaned my back against a wall and lit a cigarette, waiting.

She arrived at about twenty to eleven.

“So sorry. It’s been a rough day. In a rough week. And that’s only to mention this week.”

“What’s happened?”

“Let’s walk, is that all right?”

We headed north, still on Via Venezia. The further we got from the area of the Fort, the more the crowd thinned out. Smaller groups, couples, a few solitary walkers, a uniformed policeman or two on duty.

We walked together without speaking until we drew level with the Basilica of St Nicholas. A fellow with a Corsican mastiff passed right by us and the huge dog stopped dead to sniff at Margherita’s legs. She stopped too, stretched out a hand and stroked the dog’s head. The owner was amazed that the ferocious creature allowed itself to be touched like that, and by a stranger too. It was the first time such a thing had happened, he said. Did the lady have a dog? No, she didn’t. She’d had one, but it had died years ago.

The dog and its owner went on their way and we sat on the low wall facing the right-hand side of the basilica.

“How’s it been going for you these last few days? How about the trial?” she asked.

“Well, I hope. Monday next we may see the end of it. And how about you?” Tentative.

She paused, then spoke as if I hadn’t asked any question at all.

“In the places where they teach you to knock off drink they also explain how to resist the temptation to backslide. In the first year after treatment an awful lot of people relapse, and even after that it’s very frequent. It was something they told us over and over again. There will be difficult moments – they told us – when you will feel depressed, you will have a terrible nostalgia for the past or fear of the future. At those times you will feel the urge to drink. An urge you feel you can’t resist, that will sweep over you like a wave. But it’s not irresistible. It seems so to you because at that moment you are weaker. But it really is just like a wave. A wave of the sea only submerges you for a second or two, even if when you are under water it seems like eternity. You come out easily enough if you don’t panic. So remember – they said – that at such moments you have only to stay calm. Don’t give way to panic, remember that your head will soon come out from under because the wave has passed. When you are struck by the overwhelming impulse to drink, do something to make the seconds or the minutes pass, or however long the crisis lasts. Do exercises, run two miles, eat a piece of fruit, call up a friend. Anything that makes the time pass without thinking.”

I remained silent, fearful of what was coming next.

“It has happened to me several times, as it has to everyone. Aikido has helped me. When the wave came, I put on my kimono and went through the technical moves, trying to concentrate only on what I was doing. It worked. When I finished training I’d forgotten the urge to drink.

“With time those moments have become rarer and rarer. For at least two years I hadn’t had one.”

I lit the cigarette I’d been holding between my fingers for several minutes. Margherita went on in the same tone of voice, gazing at some indeterminate spot before her.

“There’s someone in my life, there has been for nearly three years. He doesn’t live in Bari, and maybe that’s why it has worked for so long. We see each other at weekends, either he comes to me or I go to him. Last weekend he came here. I had already mentioned you. Casually, as one might normally, and at first he didn’t mind. Or if he did he didn’t say so.”

She turned slightly towards me, took my cigarette and smoked quite a lot of it before giving it back.

“However, I don’t know how, but the discussion cropped up again last Saturday. That is, not so much a discussion as a jealous scene. Now, I should tell you that he is not a jealous person. He’s quite the opposite. So I was taken aback and reacted badly. Very badly. We had been together, in a word we’d made love ...”

I felt a stab in the guts. Instant fog in the brain for I don’t know how long before I could grasp what she was saying again.

“... and then I told him that I’d never have expected him to say such things. That I was disappointed in him and so on. He got back at me by calling me a hypocrite. I was lying when I said that you were just a friend. Lying not just to him but to myself, which made me even more of a hypocrite. And I was reacting so violently just because I knew he was right. We argued most of the night. In the morning he said he was leaving me. That I must get my ideas straight, and try to be honest with him and with myself. After that we could talk about it again. He went off and I stayed put, sitting on the bed, my mind in a turmoil. Unable to think. The hours passed like a hallucination, and of course I got the urge to drink. A mad craving, such as I’d never had since I gave up. I tried putting on my kimono and doing some training, but there was no drive behind it. I had only this craving to drink, to feel good, to drown the turmoil in my head, to shuffle off responsibility and duty and effort, the whole bloody lot. Shit!

“So I went downstairs, got in the car and drove to Poggiofranco. You know that big bar that’s open round the clock, I can’t remember what it’s called, where they sell wines and spirits?”

I knew the bar and nodded. My mouth was dry, my tongue stuck to my palate.

“I went in and asked for a bottle of Jim Beam, my favourite. At that point I felt calm. Deathly calm. I went home, got a big tumbler and went out onto the terrace. I sat down, broke the seal of the bottle – you know that lovely snap when you open a new bottle? – and helped myself to three fingers of bourbon, for a start. I did it slowly, watching as it poured into the glass, the colour of it, the reflections. Then I raised the glass to my nose and breathed in deeply.

“I sat for a long time staring at that glass, with thoughts whirling in my head. You’re a naughty girl. You’ve always been one. You can’t fight your own destiny. It’s useless. Several times I raised the glass to my lips, looked at it and put it back on the table. I was sure I’d drink it in the long run so I might as well take it slowly.

“Darkness fell and there I still was with that glass of bourbon. I felt like filling it some more. I put it down on the table and poured, very slowly. Halfway, two-thirds, right to the brim. And still I went on pouring.

“Very gradually the liquid began to overflow, and I watched it dribbling down the outside of the glass, then spreading over the table, dripping onto the floor.

“When the bottle was empty I set it down on the table. I took the glass between finger and thumb and slowly tipped it, without lifting it. It began to empty. Very, very slowly. As it emptied, I tipped it more. Finally I turned it upside down.”

I passed my hands across my face, breathing at last. I realized my jaws were aching.

“At that point I got up, fetched a bucket and floor-cloths and cleaned everything up. I put the rags and empty bottle into a bin-liner, went downstairs and threw the lot into the rubbish. I wanted to call you, but it didn’t seem right. I had to deal with this on my own, I thought. So I just sent you that message.”

She stopped abruptly. We were silent for a long time, sitting on that wall. I was burning with questions. About him, of course. What had happened after that evening? Where had she been today? Had they met again, and talked, and so on?

I asked none of them. It wasn’t easy, but I didn’t ask a single question. All the time we were sitting there and after, walking across the city to our building. Until the moment came to part, at her door. Then it was she who spoke.

“What do you think of me, after what I’ve told you?”

“What I thought before. It’s just a bit more complicated.”

“Would you like to come in?”

“No, not this evening. Don’t misunderstand me, it’s just that—”

She interrupted me, speaking quickly. Embarrassed.

“I don’t misunderstand you. You’re right. I oughtn’t even to have said it. Did you say the trial ends on Monday?”

“Most likely. It depends on one last check-up ordered by the court. If certain documents arrive in time, then we should wrap it up on Monday.”

“Will you be speaking in the morning?”

“No, I don’t think so. Almost certainly the afternoon.”

“Then I’ll almost certainly manage to come. I want to be there when you speak.”

“I’d like you to be there too.”

“Then ... goodnight. And thanks.”

“Goodnight.”

I was already on the stairs.

“Guido ...”

“Yes?”

“I did go to him afterwards. I told him he was right. About the hypocrisy – mine – and all the rest.”

She paused briefly, and when she spoke again there was an unfamiliar timidity in her voice.

“Did I do right?”

I took a deep breath and felt a knot dissolving in the pit of my stomach.

I told her yes, she had done right.
