A number of sheep has been savaged or killed, and Inspector Crossley is convinced that a very big cat like a puma is at large in the area. To Blaketon it looks more like the workings of a dog and Greengrass' lurcher Alfred seems to be the culprit. Kate Rowans starts in her new job at Dr. Radcliffe's surgery in Whitby, although she feels as if she is being kept outside deliberately. Not by Dr. Radcliffe himself, but by his receptionist Christine Ferguson. Meanwhile Greengrass has settled his outstanding account with the Inland Revenue in his own, very unique way.

Jeb Hunter is attacked and robbed in his own home and suspicion falls on Errol Jones, an old acquaintance of PC Rowan from London, when a ballpoint pen belonging to him is found on the scene of the crime. It does not do any good to Jones' case that he is black. The talk of the village is the annual cricket match between Aidensfield and Whitby, and Greengrass is of course accepting bets on the outcome in addition to selling pesticides and fertilizers. He gets a special interest in Jones when he learns that he is good at playing cricket. And he is not the only one, but for quite another reason. Nicks mother Ruby is back in Aidensfield much to the dismay of sergeant Blaketon.
