The death of businesswoman Georgina Webster, who falls from her horse during a fox hunt, turns out to be more than an accident when the leader of the hunt is sent a letter to that effect. Investigating, Dalziel and Pascoe discover someone planted gunpowder in a hedge shortly before her death, causing her horse to be startled and throw her off. As the local SABS group come under investigation, Dalziel discovers that the daughter of the huntsmaster is in fact a saboteur, and may hold more of a grudge than her compadres.
