They Do It with Mirrors: A Miss Marple MysteryPaperback, 1 April 2011

In this exclusive authorized edition from the Queen of Mystery, the indomitable Miss Marple investigates some rather deadly doings at a rehabilitation center for delinquents.

Miss Marple senses danger when she visits a friend living in Stoneygates, a rehabilitation center for delinquents. Her fears are confirmed when someone shoots at the administrator. Although he is not injured, a mysterious visitor is less fortunate--shot dead simultaneously in another part of the building.

Pure coincidence? Miss Marple thinks not, and must use all her cunning to solve the riddle of the stranger's visit ... and his murder.
