The Baker Street Letters by Michael Robertson

Protagonist: Reggie and Nigel Heath
Setting: London and Los Angeles
Rating: 4.6
Reggie Heath and his law firm have moved into a building on Baker Street. In the lease comes a stipulation that they answer all letters written to 221b Baker Street -- the fictional address of the fictional Sherlock Holmes. His brother Nigel, suspended from practicing law, is supposed to answer the letters, sending a form reply. But Nigel becomes too caught up in a set of letters -- the first one dating back 20 years, when an 8-year-old girl from Los Angeles wrote to Sherlock, asking for help in finding her missing father.

Soon, Nigel is on a plane to Los Angeles. Reggie follows him, but seems to always be two steps behind Nigel. Death also seems to follow Nigel -- he’s accused of a murder in London and then another in L.A. Can Reggie find him before he gets in even deeper?

It's always tricky writing a book about Sherlock, but Robertson gives it a neat twist. This is an engaging debut about two brothers, often at odds, who come together to solve a crime (or two, or three). The book has already been optioned by Warner Bros. for a television series, and the second in the series, The Brothers of Baker Street, is due to be released soon.
