Moving on to dating other Holmes stories:
- REIG - April 1887. The Lyons telegram is the 14th, but the Reigate case starts on the 25th.
- SILV - July 7-12, 1887
REIG has had multiple titles over the years: "Reigate Squire", "Reigate Squires", and "Reigate Puzzle." It depends on what collection or edition you have, what the title will be. This case has one of the more interesting beginnings, because Watson mentions a great international case, concerning the Netherland-Sumatra Company and the colossal schemes of Baron Maupertuis, which Holmes investigated in France. He was apparently there for two months, working 15 hour days, for four days at a stretch. Yet Watson was not with him, and we are given no explanation for why. It could be that Watson got a medical job and couldn't go to France for that long. (I'm thinking of locum work, filling in for other doctors, rather than a practice of his own.) Brad Keefauver thinks that Watson was romancing a new wife and Holmes wanted to get away starting in February. But I don't subscribe to theories about Watson constantly getting married, let alone the idea that they were all fake marriages. It could be that Holmes asked Watson not to come, that he secretly planned to use cocaine to sustain that crazy pace, and he knew that Watson would object to the drug.
