For some reason, Watson failed to date most of Holmes' adventures, and we must therefore make a guess at the chronology of these stories through their allusions to other cases.
The first of these tales, The Conk-Singleton Forgery Case, is mentioned by Watson. He gives no other details in The Adventure of the Six Napoleons, and the story was presumably withheld from the public on account of Holmes' brush with the police as described here. The story provides excellent examples of Holmes' skill in deduction from seemingly trivial observations, as well as details of his methods of working a case.
The next story, The Strange Case of James Phillimore, is likewise mentioned in passing by Watson. James Phillimore is described as stepping into his house to retrieve his umbrella, never to be seen more in this world. This brief description implies a somewhat supernatural twist to things, but the truth of the matter is even more surprising. The open antagonism between Sherlock Holmes and some officers of the Metropolitan Police Force may come as somewhat of a surprise to those who have always regarded him as an unflagging ally of the official guardians of law and order.
In The Enfield Rope, we enter unknown territory.Watson never alluded to this case. The principals here were far too well-known to Watson's public to allow of this case's publication, even with pseudonyms, and respect for the British Establishment would have restrained Watson in this instance. Holmes' sense of the dramatic is shown here, and his admiration and liking for a member of a part of society that was often shunned at that time shows a human, more attractive side to Holmes than is often portrayed by Watson.
The Bradfield Push is an early case of Sherlock Holmes, where Watson loses both his heart and his watch. Holmes can retrieve one, but not the other.
