Peril at End House (Hercule Poirot Series)

Nick is an unusual name for a pretty young woman. And Nick Buckley has been leading an unusual life of late. First, on a treacherous Cornish hillside, the brakes on her car fail. Then, on a coastal path, a falling boulder misses her by inches. Safe in bed, she is almost crushed by a painting. Upon discovering a bullet hole in Nick's sun hat, Hercule Poirot (who had come to Cornwall for a simple holiday with his friend Captain Hastings) decides that the girl needs his protection. At the same time, he begins to unravel the mystery of a murder that hasn't been committed. Yet.
