The wife of A.B. Helmet (full name unrevealed) was a former singer and an old lover of 88 Keyes.
Shortly after she married the millionaire A.B. Helmet, Mrs. Helmet hired 88 Keyes and his accomplices to kill her new husband, agreeing to pay them $1,000 each. Upon her husband's death, Mrs. Helmet received a life insurance settlement of $200,000.
After killing his accomplice Jinny Lynn, Keyes met up with Mrs. Helmet and the pair fled west. After two days of driving without rest, Mrs. Helmet fell asleep at a railroad crossing near Pawnee, Oklahoma (Chester Gould's hometown). 88 then left the widow in her car to be struck and killed by a passing train.
- Mrs. Helmet received a sizable insurance payment upon her husband's death, but no mention was made of her inheriting his estate.
