Murder's a knockout! Despite her misgivings and general distaste for fighting sports, Mrs. Ginger Reed, also known as Lady Gold, agrees to attend a boxing match to support her adopted son's cousin, a street fighter who's quickly risen in the ranks. But when his opponent, the presumed champion-to-be, drops out and then drops dead, Ginger and her husband, Basil, a chief inspector at Scotland Yard, investigate. Was the fighter dead because of sports-betting gone awry? Were London gangs involved? And has an old, but newly present danger returned to threaten the Reed family? When one of their own falls prey, the gloves come off and the fight becomes personal. Can Ginger and Basil save their family and stop a killer before the towel is thrown in the ring?
