The Welsh Borders in the 1950s Salmon and trout aren't the only species under threat in this tale of love, hate, murder - and fly fishing.

When a local boy is found drowned in the River Tossy, most people assume it's an accident - and few tears are shed for a uniquely nasty individual.

But Meg Marsden and her husband Andy, come recently to the riverbank village of Coedafon for the fishing, gradually realise that there are equally unpleasant people still alive - and one or more is a murderer. Peaceful though the village may be on the surface, it's only a matter of time before other bodies are dragged from the river.

In the face of police indifference, Meg, narrowly surviving several vicious attempts on her life, finally unearths the horrifying truth - so life returns to normal. Or does it?
