Accusations of unsportsmanlike conduct on the river are bedevilling the Midsomer game fishermen, and Barnaby has to interview elegant widow Isobel Hewitt, a spendthrift, fast-living, Jaguar-driving 75-year-old, when another lady fly-fisher accuses her of a violent assault.

Troy has a theory that Scholey was the killer and has made his suicide look like murder, but will that be the end of the affair?
