Miss Marple is told that her old friend, Carrie, is in danger and she goes to stay with her at Stoneygates, a home for maladjusted adolescents. While she is there, tragedy strikes as Carrie's stepson is shot dead. There are at least seven suspects and two more murders follow. But the man with the obvious motive has a cast-iron alibi, as he could hardly be in two places at once -- or could he? June Whitfield stars as Miss Marple, the indomitable amateur detective.
