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 William Morrow Paperbacks. In Christie’s gripping international thriller Destination Unknown, a woman at the end of her rope chooses a more exciting way to die when she embarks upon an almost certain suicide mission to find a missing scientist.
