What Happens, Part by Part (Contains Spoilers)
A body on the rug
At Gossington Hall, the maid screams that there is a body in the library. Colonel Bantry is stunned, and gossip spreads quickly in the village of St Mary Mead. The dead girl is wearing heavy makeup and a cheap white evening dress. Dolly Bantry sends for Miss Marple, who notices odd details, such as the girl's bitten fingernails.
The Majestic Hotel
The girl is identified as Ruby Keene, a dance hostess at the Majestic Hotel in the seaside town of Danemouth. Her cousin Josie, who works at the same hotel, identifies the body. Ruby had become close to Conway Jefferson, a rich man in a wheelchair, who planned to adopt her and leave her a large fortune.
Suspects
Jefferson's son-in-law Mark Gaskell and daughter-in-law Adelaide had expected to inherit his money, so they had motives. A film man, Basil Blake, who lives near the Bantrys, is also suspected, especially after Colonel Bantry's reputation suffers. Miss Marple studies the hotel and the dance floor.
A second death
A burned-out car is found in a quarry with the body of a teenage girl inside. She is identified as Pamela Reeves, a schoolgirl who went missing on the same night. Miss Marple connects the two crimes and considers the girl's interest in films and a promised screen test.
The solution
Miss Marple reveals that the body in the library was not Ruby at all but Pamela, dressed to look like her. Mark Gaskell and Josie Turner, who were secretly married, killed Pamela and then Ruby to stop Ruby from inheriting Jefferson's fortune. Josie deliberately identified the wrong body. Ruby's body was burned in the car. The bitten nails and the dress gave the plan away.
5 Key Takeaways
