The Winning Clue is a mystery novel written by James Hay. Enid Withers is discovered deceased and amateur investigator Lawrence Bristow takes up on a challenge to unravel the mystery of her murder. Excerpt: "Mr. Bristow, however, was not allowed to rest half an hour. Instead, he was called upon to consider a phase of the Withers murder more amazing than any of those so far uncovered. Barely ten minutes after his conversation with the clerk of the Brevord, Mattie announced that two gentlemen were waiting to see him, one of them being the chief of police. When Bristow stepped into the living room, Greenleaf introduced the stranger. He was Mr. Withers—Mr. George S. Withers, husband of the murdered woman. He was of the extreme brunette type, his hair blue-black, his black eyes keen and piercing and always on the move. Bristow got the impression in looking at him that all his features, the aquiline nose, the firm, compressed mouth, the large ears, were remarkably sharp-cut."
