Murder of Innocence is the second episode of the fifteenth series of Midsomer Murders and was originally aired on 21st March 2012.
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.
Tropes:
- Had to Come to Prison to Be a Crook: Tragically, Grady Felton actually was innocent of the crime he was sent to prison for. But the injustice of his wrongful imprisonment left him so embittered that he plotted and executed a spree of murders against everyone he considered to have wronged him.
- Letterbox Arson: A murder is attempted by pouring petrol through the letterbox of a cottage and following it with a flaming rag.
- Magic Plastic Surgery: Grady Felton's cellmate had surgery to make himself look exactly like Felton should do.
- Roaring Rampage of Revenge: Grady Felton seeks vengeance on everyone involved in sending him down, including Jones.
- Spotting the Thread: Grady Felton's cellmate had surgery to make himself look exactly like Felton should do, but he couldn't change his fingerprints and those fingerprints were still on the police database with his original name. This is what allows Barnaby to figure out that the Felton they'd been watching was an imposter.
