Each of the tales I have selected to recount here was mentioned by Watson in previous adventures, but only in passing, and the sketchy references have long been a source of curious speculation by students of the work of Sherlock Holmes.
- The Case of Colonel Warburton's Madness is one of the few cases recorded by Watson as being one that he introduced to Holmes (The Engineer's Thumb being the other).
- The Mystery of the Paradol Chamber is strangely named, and the mystery itself is a strange one where Holmes' talents are needed to unravel a classic "locked room" murder puzzle.
- Finally, the definitive story of The Giant Rat of Sumatra has come to light. There are obvious reasons why this story was withheld from the public for so long. Even with the pseudonyms that have been so obviously employed, this story could have shaken the respectable world of English politics to the core if released.
These latest tales that I have unearthed will, I am confident, provide both enjoyment and instruction to all those who study and cherish the work of Sherlock Holmes. I hope to provide even more such tales, following further exploration of the contents of the deed box.
