A killer is rarely satisfied with just one crime.

A lord who mysteriously disappears... a newlywed woman who fears her former lover... a strange encounter on a train... a bizarre murder where the culprit is sought... a man who changes his behavior... a truly cunning woman... a necklace hidden in a basket of cherries... a young woman pretending to be a duchess... an arrest for the murder of a mystery story writer... an impressive marriage proposal... the emerald of a maharaja... a soprano who hates a baritone to death...

Twelve masterful mystery stories, including "Philomela's Farmhouse," which for years was Christie's most adapted short story. Twelve puzzles for strong solvers, signed by the ultimate queen of the detective novel.
