Rocket to the Morgue

A BOMB IN THE MAIL, POISONED CHOCOLATES, A LOCKED-ROOM KNIFING, A WEIRDLY DISGUISED KILLER. A deadly net of danger tightened around Hilary Foulkes as an unseen enemy made constant, bizare attempts on his life. Detective Terry Marshall and his unusal assistant, the inquisitive nun, Sister Ursula, worked desperately against the clock to break the case-- for Foulkes's luck was due to run out any second! Match wits with master of mystery in this fiendish, lively puzzler--an all-time classic from ANTHONY BOUCHER.
