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. Poirot must solve a perplexing case of midair murder in Death in the Clouds when he discovers that the woman in seat two of the airborne aeroplane he’s traveling on is quite unexpectedly—and unnaturally—deceased.
