Mrs Lorrimer asks Poirot to visit her, tells him that she has just been diagnosed with a terminal illness, and that she wishes to confess to the killing both of her husband and of Shaitana. Poirot refuses to believe her psychologically capable of spontaneous murder, and thinks that she is protecting Anne. Mrs Lorrimer reluctantly discloses that she had actually seen Anne commit the crime, but feels sympathy for a young girl who is just starting out in life. The next day, each of the other suspects receives in the morning's post a confession and suicide note. Battle informs Poirot by telephone that although several people had rushed to her house it was too late, and she had died of an overdose. Poirot is again suspicious, as he knows that Anne had visited the previous night. He discovers that Mrs Lorrimer could not have sent the letters.
