The year ’87 furnished us with a long series of cases of greater or less interest, of which I retain the records. Among my headings under this one twelve months I find an account of the adventure of the Paradol Chamber, of the Amateur Mendicant Society, who held a luxurious club in the lower vault of a furniture warehouse, of the facts connected with the loss of the British barque Sophy Anderson , of the singular adventures of the Grice Patersons in the island of Uffa, and finally of the Camberwell poisoning case. In the latter, as may be remembered, Sherlock Holmes was able, by winding up the dead man’s watch, to prove that it had been wound up two hours before, and that therefore the deceased had gone to bed within that time⁠—a deduction which was of the greatest importance in clearing up the case. All these I may sketch out at some future date, but none of them present such singular features as the strange train of circumstances which I have now taken up my pen to describe.
