The Queen of Mystery has come to Harper Collins! Agatha Christie, the acknowledged mistress of suspense--creator of indomitable sleuth Miss Marple, meticulous Belgian detective Hercule Poirot, and so many other unforgettable characters--brings her entire oeuvre of ingenious whodunits, locked room mysteries, and perplexing puzzles to Harper Paperbacks. A most unusual series of crimes at a student hostel intrigues Inspector Poirot in Christie's Hickory Dickory Dock, especially when a simple case of kleptomania paves the way to murder.
