The Sign of Fear - The adventures of Mrs.Watson with a supporting cast including Sherlock Holmes, Dr.Watson and Moriarty

Sherlock Holmes said that Mary Morstan might have been most useful in detective work if she had only remained single. She - had a decided genius - that way. So, bored with being at home while her husband is away helping Holmes catch criminals, Doctor Watsons wife decides to have a go at the game herself. In this she is ably assisted by her friend Emily Fanshaw who likes to play a transvestite role occasionally.
