Notes from the Dispatch-Box of John H. Watson M.D.: Some Untold Adventures of Sherlock Holmes - Dispatch-Box

Another discovery from the vaults of Cox and Co., the old London bank which had forwarded the Deed Box of John H Watson to the author last year. The Dispatch Box contains all manner of illuminating documents about Messrs. Holmes and Watson.

Of particular interest are what the author refers to as The Affair of the Vatican Cameos, the Reigate Poisoning Case, with a shocking conclusion, and a document apparently written by the man Holmes himself called 'the fourth smartest man in London', John Clay.
