无辜的谋杀

When a barrister is killed in Midsomer, suspicion falls on convicted murderer Grady Felton. Grady has just returned to the village where he committed the murder years ago amid much anger from locals. But Grady has a solid alibi. Barnaby suspects he is working with an accomplice - until Grady himself is targeted in an arson attack.In 1994 teenager Grady Felton was jailed for killing land-owner Ted Denning's son Daniel, who caught him poaching. Ever declaring his innocence Grady is now back in Binwell, swearing vengeance on everybody who had a part in sending him down. However he has alibis for the deaths of the prosecuting and defending barristers in his case and is himself hospitalised after Denning's daughter Deirdre and reckless employee Kyle Gideon torch his house. After another murder Barnaby suspects that Grady has an accomplice, and then pathologist Kate Wilding makes a bizarre discovery, enabling him to solve the murder of innocence.
