劇情：The body of a young woman was abandoned in the library of Gosington Hall, which was the home of Jane Marple's friend Dolly Bantry and her husband Arthur. The arrogant police chief Melchett suspected that he had a connection with Basil Blake, a young man with artistic flair in the area, but when Melchett visited him, Blake dismissed it. Then, Superintendent Harper called from the coastal town of Dammouth. Ruby Keen was a young girl who worked as a dancer at the Majestic Hotel there. She went missing, and her cousin Josie Turner confirmed that the body belonged to Ruby. Ruby has the support of millionaire Conway Jefferson, whose own son and daughter died in a space-time raid during the war, and he wants to adopt her. His son-in-law Mark Gaskell and daughter-in-law Adelaide had different reactions to this news. Miss Marple was convinced that the solution to Ruby's murder case might be found in the hotel, and she and Dolly booked a suite for investigation.展開
