A Study in Scarlet
One aspect of the Game in its traditional form is the effort to resolve or explain away contradictions in the Holmes canon, such as the location of Watson's war wound, which is described as being in his shoulder in "A Study in Scarlet" and in his leg in "The Sign of Four", or his first name, given as John in "A Study in Scarlet" and "The Problem of Thor Bridge" but James in "The Man with the Twisted Lip".
