【중국 직배송】 중국 서적 라이븐워스 사건

Price: 49.00. A millionaire is shot in the back of the head in his library with his own gun. He was reviewing a book he planned to publish before his death. The library door was locked, with no signs of forced entry or struggle. No one else was in the house except the deceased's two nieces and his servant.
During the investigation, protagonist Raymond discovers that all the evidence points to Mary, one of the millionaire's nieces. But Raymond feels she is hiding something in her statement. In further investigation, Raymond uncovers the secret hidden behind it.
The author deliberately misleads the reader, making the process of solving the case convoluted and bizarre. Many plots and elements in the novel have been borrowed in numerous subsequent detective novels, such as locked-room murders, lost keys, fragments of burned letters, and missing maids.
