Can't get enough Sherlock Holmes? Two stories from the files of Dr. Watson have just been collected together for the first time! "Sherlock Holmes and the Case of the Missing Date" - a lost treaty surfaces which threatens the peace of all of Europe, and only Holmes can save the day! "Sherlock Holmes and the Case of the Viscount's Butler"- did the butler really do it? He denies it, but is he telling the truth?
