* Though his name did not appear on the census of 1861, there are indications that Whicher was living in this house by 1860. In a police circular of 1858 he asked fellow officers to inform him, at Scotland Yard, if they saw a twenty-four-year-old gentleman who had gone missing, 'mind supposed affected'; two weeks afterwards a private advertisement appeared in The Times requesting news of this same young man, with his 'rather pale full face', and offering a PS10 reward - it was presumably placed by Whicher, but it asked that information be passed to 'Mr Wilson' of 31 Holywell Street. The pseudonym concealed the fact that the police were looking for the wan gentleman. 'The tricks of detective police officers are infinite,' observes the narrator of The Female Detective. 'I am afraid many a kindly-disposed advertisement hides the hoof of detection.' A year later, in 1859, the Commissioner's office put out a request for information about a white, wolf-breed dog that had gone missing from 31 Holywell Street. A lost dog was not usually a matter for Scotland Yard - maybe the white wolfhound belonged to Whicher's landlady (Charlotte Piper, a widow of forty-eight with a private income) or to the detective himself.
