"The Winning Clue" by James Hay is a murder mystery novel written in the early 20th century. The story centers around the investigation of the brutal murder of Mrs. Withers, unraveling a tangled web of relationships, jealousy, and secrets. The main character appears to be Lawrence Bristow, a lamed man with a knack for solving crimes, who becomes intricately involved in the case alongside local police. The opening of the book introduces a chilling scene on Manniston Road, where Bristow first hears a woman's terrified cry for help. Rushing to assist, he discovers the lifeless body of Mrs. Withers in an unsettling pose on a couch, indicating foul play. As neighbors gather, Bristow takes charge, urging swift action to preserve the crime scene. What unfolds is Bristow's engagement with several key suspects, including the frightened sister Miss Fulton and humorously ineffective police officers. The narrative hints at deeper familial tensions and possible motivations for murder, laying a complex foundation for a classic whodunit. (This is an automatically generated summary.)
