More From the Deed Box of John H. Watson M.D.. The Deed Box, #2

Hugh Ashton has been digging deeper in the deed box that originally belonged to Dr Watson, the friend and colleague of the celebrated detective Sherlock Holmes. He has unearthed three more tales referred to in the original books, but never before released to the public: Colonel Warburton's Madness; the Paradol Chamber; and the Giant Rat of Sumatra. 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).
Taking place in a seemingly innocuous suburban setting, it is nonetheless a tale of dark secrets and hidden evil. Holmes' skill at disguise is never seen to better advantage. Watson himself likewise shines as an investigator of more than average competence. 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.
Religion plays a very minor role in most of the cases described by Watson - it is interesting to see here that Holmes claims to have memorised the churches and incumbents of all the Roman Catholic (at least) churches in the English Home Counties. 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. The cooperation of the Royal Navy with Holmes in the solving of this bizarre mystery is another aspect that would also have been kept secret, possibly at the behest of Mycroft.
