Brothers of Baker Street by Michael Robertson, Pan Macmillan, $32.99
Reggie and Nigel Heath are brothers who practice law from the offices of 221b Baker Street, London an address better known as the home of fictional detective Sherlock Holmes.
The premises come with an obligation to reply to all the loonies who write to Holmes, of which there are a surprising number considering that even if he wasn't entirely imaginary, he would most certainly be long dead.
But one of those strange correspondents comes in handy when Reggie takes on the defense of a London taxi driver accused of murdering two American tourists.
Things are looking shaky for the poor old cabbie until the mysterious writer sends in several helpful tips.
The Brothers of Baker Street is an off-beat whodunit with great dollops of old fashioned British charm and humour, soaring surprisingly to a cinematic peak which brings central London to a standstill.
