Locked Rooms is the eighth book in the Mary Russell series by Laurie R. King. It was published in 2005. Unlike King's previous Mary Russell novels, Locked Rooms is split into 5 separate "books". The books alternate between the familiar Mary Russell first-person narrative and a third-person narrator following Sherlock Holmes. The events of the novel follow directly that of The Game. Mary Russell and Sherlock Holmes sail to San Francisco to close up the house and businesses that Mary inherited after her family's death. Throughout her adolescence and adulthood, Mary has blamed herself for the family's fatal automobile accident. A puzzling codicil to the Russells' will, a break-in at the family house, and a failed attempt on Mary's life quickly draw Holmes and eventually Mary into an investigation of the real cause of her parents' death. Holmes and Russell team up with a former Pinkerton agent Dashiell Hammett, several residents of Chinatown, and a cast of irregulars to solve the mystery that has plagued Mary for ten years.
