Nine years after a series of unsolved murders at Midsomer Worthy, a new death which follows the same pattern (a girl is found strangled in the woods) leads to fears that the serial killer is back in business. Barnaby and Troy look out the old files in dealing with the first new murder - and then others follow.

Troy is in the Midsomer Worthy cricket eleven for the annual match against Fletchers Cross, so he is on the spot when the wife of Robert Cavendish, the Team Captain and a big local landowner, is found bludgeoned to death with a cricket bat. As often happens, the death toll mounts before the killer can be unmasked. Why should the cricket team's scorer be stabbed to death with a Nazi dagger at the following match? Cavendish, as a mine owner, may have been responsible for the 'accidental' deaths of two of his employees in years gone by. If someone is out for revenge, who is it? Meanwhile, a protest march to maintain footpaths across Cavendish's land finds a foot-bridge has been sabotaged, and their leader takes a ducking...

The sleepy village of Martyr Warren is invaded by quarrelsome New Age travellers, some of whom fall out with Hector Bridges, a local magistrate. The police are well aware of the tensions, but matters come to a head when Hector is found shot dead. It quickly appears that he was feared by almost everyone in sight, including his own family. And there is more to the travellers than meets the eye - one of them is a former British army officer who fought alongside Hector in the Falklands War... Then (as so often happens to Barnaby and Troy) another dead body is found, this time that of an old man at the travellers' camp.Meanwhile, Barnaby is not feeling in full fighting trim for murder investigations, as Joyce has put him on a strict diet to lose weight.
