If You Like Sherlock Holmes, read these books

Fans of all-things Sherlock will enjoy Moriarty Returns a Letter (2014) by Michael Robertson, the fourth in his 'Baker Street Mystery' series. The premise - a law firm at 221B Baker Street still receives letters addressed to Sherlock Holmes and is required by the lease to reply to all of them. A descendent of Moriarty, Holmes' arch-enemy, returns to seek revenge in this outing. The fine line between the fictional stories and the confusion starting over a century ago about whether Sherlock Holmes existed or not, with some believing that Sir Arthur Conan Doyle as literary agent to the real Dr. Watson, is explained. This is a series best read in order. Start with The Baker Street Letters (2009)
