Constable Hugh Collins doesn't mind incurring minor injuries running a police boxing program as a safe, legal alternative for street-fighting, meanly youth gangs. Inspector Robinson makes him arrest boxer protege Tom Derrimut, who has mixed feelings about informing to get clear as logical suspect for the murder on the rival gang's leader, pointing to their new gang leader Kevin Bradley and to the police themselves as the victim fatally stabbed a constable with kids. Tom also earns good money fighting at Arthur Biggs's boxing tent, which Phryne soon finds systematically rigged, flirting with genuine champion Giorgos the Greek. However somehow Tom's lurking, doting kid brother Dan and Arthurs' giant wife are also involved, even a long-killed fighter of aboriginal blood proves key.
