Someone is blackmailing a local supermarket chain. And getting away with it, thanks to a very clever payoff method involving hole-in-the-wall bank machines and a bit of glaring police incompetence. When the blackmailers descend on Eddathorpe Robert Graham is called in. He thinks it's an inside job - and sets out to prove it. He doesn't know the case is going to escalate from fraud to murder. And that its unravelling could change his life . . .

Once again, sleepy, seedy Eddathorpe hides its secrets well - and once again, East Anglia's magnet for murder, Robert Graham, teases them out with his own unique combination of solid policework and brilliant intuition.
