Decorative letter crimes

A brief about the novel Hercules Poirot's dinner was interrupted in a London café when a young woman confided in him that she was about to kill. The woman was extremely panicked but begged Poirot not to try to find her killer and punish her. She insisted that justice would be achieved once she died. Later that night, Poirot learned that three guests at a fancy hotel in London had been killed, and cuff buttons had been placed in each of their mouths. Is there a connection between the terrified woman and the murders? While Poirot was trying to solve that mystery, the killer was preparing another room in the hotel for his fourth victim. A very mysterious puzzle that will only be solved by the talented Belgian detective and his small gray cells.
