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.

Agatha Christie is the most widely published author of all time, outsold only by the Bible and Shakespeare. Her books have sold more than a billion copies in English and another billion in a hundred foreign languages. She died in 1976, after a prolific career spanning six decades.
