This is the second novel in a spectacular new series about two brother lawyers who lease offices on London’s Baker Street–and receive mail addressed to Sherlock Holmes.

The first Sherlock Holmes letter barrister Reggie Heath answered cost him most of his personal fortune, all of his Baker Street chambers clients, and quite possibly Laura Rankin, the love of his life. But Reggie intends to earn all of it–the money, the career, and the love–back again. His latest client is the driver of one of London’s famous black cabs, accused of murdering two American tourists. But while Reggie is working on that case, the letters to Sherlock Holmes are piling up–including one from someone who claims to be the descendant of Professor James Moriarty.
