Sherlock Holmes joins wife Mary Russell as she watches over the young actresses cast in Fflytte Films's latest extravaganza, The Pirates of Penzance, being made on location in Lisbon and Morocco. Suddenly, the prop knives turn real and so do the pirates. The latest in a fun, durable series with two million copies in print, no less. Don't miss.

In the latest volume of Mary Russell's memoirs (after God of the Hive), Sherlock Holmes's young wife is sent to Lisbon by Scotland Yard's Inspector Lestrade. Her mission: investigate possible criminal activities of the Fflytte Film Company and the whereabouts of the studio's one-time secretary. Mary's strong personality and wit, on which fans of the series have come to rely, serve her well as she makes her way through the day-to-day frustrations and calamities involved in film production. She is joined by Holmes as the company and her investigation wend their way to Morocco. Russell's encounters with the cast and crew of Pirate King, along with her dislike of all things Gilbert and Sullivan, provide humorous conflict, while her crime-solving collaboration with Holmes, as always, gives readers a taste of their sharp intellect and clever deductions. VERDICT Recommended for series fans as well as devotees of historical mysteries.

In a foreword, King, to her credit, acknowledges the implausibility of her 11th Mary Russell novel (after The God of the Hive) by having her heroine declare, "I fear that the credulity of many readers will be stretched to the breaking point by the case's intricate and, shall we say, colourful complexity of events." If anything, this is an understatement. In the fall of 1924, Sherlock Holmes, Mary's husband, uses the threat of an impending visit from his brother, Mycroft, with whom she's at odds, to persuade Mary to travel to Lisbon, where she's ostensibly to serve as a production assistant for "a film about a film about The Pirates of Penzance." In fact, she's on covert assignment for the British government to investigate the studio behind the new film, whose releases appear to coincide with an upsurge in criminal activity. Sherlockians must wait more than half the book for Holmes to put in a cameo in this action-heavy, deduction-light installment. (Sept.)
