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.

In this official authorized edition, the normally unflappable Hercule Poirot faces his most baffling investigation: the seemingly motiveless murder of the thirteenth guest at dinner party, who choked to death on a cocktail containing not a trace of poison.

With absolutely no motive for murder found, this book will keep you guessing until the very end!
