Book excerpt: In her third book author Molly Carr has, for the moment, abandoned the Watson-Fanshaw Detective Agency in favour of discovering as much as possible about Doctor Watson. Radically different in style from her first two books, the investigation will nevertheless be of interest to students of military history, railways both Indian and British and of course all fans of Sherlock Holmes. Holmes is a household name. But where would he be without his Biographer? Beavering away in Baker Street, unknown to everyone except Scotland Yard and a few luckless criminals. It is time to put the loyal and much put upon man, Dr. John H. Watson M.D., centre stage.
