Three Complete Mystery The Mystery of the Blue Train Death in the Air What Mrs. McGillicuddy Saw! The Mystery of The Blue If Hercule Poirot had not been on the luxurey boat-train from London to the Riviera, the murder of a beautiful young woman would have gone unavenged, the disappearance of the fabulous rubies would have remained unsolved, and one of the most diabolically clever conspiracies of the era would have succeeded. Death in the Twenty-one passengers were winging their way across the English Channel. In the rear of the cabin a woman, her head lolling forward, seemed to be asleep, but she was dead. Madame Giselle - money-lender blackmailer, woman with a past - had been murdered. And the crime had been committed in M. Poirot's very presence by one of the occurpants of the airplane! What Mrs. McGillicuddy Saw!: Mrs. McGillicuddy insisted that she had seen a murder take place from her train window. A man, standing in a compartment of a train running parallel with hers, was strangling a woman. As Mrs. McGillicuddy watched, the body went limp and crumpled in the man's hands. Miss Jane Marple was willing to investigate - but first a corpse had to be found. 601 Pages
