The Kidnapping of Johnny Waverly

Poirot is called in to investigate the kidnapping of three-year old Johnnie Waverly, the son of Marcus Waverly, from his home, Waverly Court in Surrey. Prior to the kidnapping, the family received anonymous letters that threatened to take the boy unless twenty-five thousand pounds was paid. The police took little interest until the final letter which stated that the boy would be kidnapped at twelve o'clock the next day. On that day, Mrs. Waverly was mildly poisoned and a note was left on Mr. Waverly's pillow that stated, "At Twelve O'clock".
