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. Marple and Poirot both make appearances in Christie’s Double Sin and Other Stories, a sterling collection of short mystery fiction that offers double the suspense, surprise, and fun.
