<p>Sir Charles Cartwright should have known better than to allow thirteen guests to sit down for dinner. For at the end of the evening one of them is dead—choked by a cocktail that contained no trace of poison.</p> <p>Predictable, says Hercule Poirot, the great detective. But entirely unpredictable is that he can find absolutely no motive for murder.…</p> <p>The Reverend Stephen Babbington seldom imbibes, but at a gala thrown by actor Sir Charles Cartwright, he indulges in a cocktail and falls over dead. Since there is no trace of poison or foul play, the case is closed . . . until an identical death at a London party arouses the suspicions of Hercule Poirot. Also published as Murder in Three Acts. Reissue. </p>
