I know that Twain lampooned Sherlock Holmes in "A Double-Barrelled Detective Story" and referred to him briefly ("the late Sherlock Holmes") in FOLLOWING THE EQUATOR. In Stanley Weintraub's THE LONDON YANKEES: 1894 - 1914, Conan Doyle is listed among "old friends" Twain encountered in London society in the year 1900. Does anybody know where might I find more on the relationship between Twain and Doyle? Thanks, Darryl Brock
