The Hound of the Baskervilles by Simon Goodenough, Sir Arthur Conan Doyle (1984, Paperback)

Simon Goodenough created only three of these Sherlock Holmes crime dossiers and each one is a fantastic collection. The three in the series include: 1) Study in Scarlet, 2) Sign of Four, and 3) Hound of the Baskervilles. Each dossier is based on the supposedly discovered tin box of evidence that had belonged to Dr. Watson. Excerpts from Watson's diary with notes by Holmes is the main body of evidence. Then paper documents (newspaper clippings, telegrams, notes, letters, police file reports, photos, etc.) from the case are included. Also some hard evidence may be included such as the wedding ring from the Study in Scarlet. Often though, you can only find these dossiers in used condition and the "hard evidence" is missing.
A lot of work went into each dossier and believe me, they are more than
"Good Enough" . . . in fact a "must have" . . . for any Holmes collection! Until I found these I was trying to assemble my own dossiers. They have inspired me to continue that effort.
