When two bodies are discovered by the side of a fishing stream, Barnaby and Troy have yet more murders to solve. Isobel Hewitt had a zest for life that some can only hope for. She loves to drive her red Jaguar at top speed and generally enjoyed the finer things in life. Although loved by many, there were those who weren't quite so charmed by her. Margaret Seagrove was convinced that she was the member of the local fishing club using weighted lures in the local stream. Her nephew and his wife, with whom she resided, saw her as a burden now that she had spent most of her accumulated capital. The second victim is the local doctor, Duncan Goff, a well-known philanderer who had affairs with many of the local ladies. The police must first determine if both were intended victims or if one was simply in the wrong place at the wrong time.
