Hercule Poirot is vacationing on the Cornish coast when he meets Nick Buckley. Nick is the young and reckless mistress of End House, an imposing structure perched on the rocky cliffs of St. Loo.
Poirot quickly takes a particular interest in the young woman. She has recently narrowly escaped a series of life-threatening accidents. Something tells the Belgian sleuth that these so-called accidents are more than just mere coincidences or a spate of bad luck. Something like a bullet! It seems all too clear to him that someone is trying to do away with poor Nick, but who? And, what is the motive? In his quest for answers, Poirot must delve into the dark history of End House. The deeper he gets into his investigation, the more certain he is that the killer will soon strike again. And, this time, Nick may not escape with her life.
