Grave Mistake: A spa stay turns into a homicidal holiday...A bit snobbish and a trifle high-strung, Sybil Foster prides herself on owning the finest estate in Upper Quintern and hiring the best gardener. In fact, she is rapturous over the new asparagus beds when a visit from her unwelcome stepson sends her scurrying to a chic spa for a rest cure, a liaison with the spa's director...and an apparent suicide. Her autopsy holds one surprise, a secret drawer a second. And Inspector Roderick Alleyn, C.I.D., digging about Upper Quintern, may unearth still a third...deeply buried motive for murder.
Spinsters in Jeopardy: An exotic end for an English spinster. En route to a family vacation on the French Riviera, Inspector Roderick Alleyn glimpses from the train a shocking tableau. In a moonlit window a white-robed figure raises a knife to a woman's shadow. Thus begins his incognito exploration of the Chateau of the Silver Goat...where a jet-set cult's 'Way of Life' could spell death for a maiden lady of a certain age-and even for Alleyn's own young son unless he can unveil its illicit mysteries...
Overture to Death: Amateur actors set the stage for murder...Who in the quiet village of Chipping would kill wealthy spinster Idris Campanula? Plenty of people, among them her fellow cast members from a troubled charity production. Miss Campanula was a spiteful gossip, gleefully destroying others' lives merely for her won excitement. But once Inspector Roderick Alleyn arrives, he quickly realizes that the murderer might have killed the wrong woman-and may soon stage a repeat performance.
