Inspector Lewis (Kevin Whately) is retired and living with Laura (Clare Holman) when a 2001 case of his is reopened due to cross-contamination of DNA evidence.
Graham Lawrie was convicted of killing three policeman. He has always claimed innocence. The lab that did the tests has now been found to have been wrong in two other cases. Worse, a police officer has just been killed in a similar way, with a hammer.
Lewis believes he had the right man,and he thinks the latest murder is a copycat murder or perhaps done by an accomplice. As the senior officer now, Hathaway is sensitive to the problem but knows he has to be unbiased in the investigation.
He learns that some evidence was not presented in 2001 that would have cast doubt on the Lawrie's guilt -- that he had an alibi for one of the murders. Lawrie is set free, and another officer is killed.
Lewis comes out of retirement to assist in the case.
Good episode, interesting mystery with a neat twist. Lewis and Hathaway work well together even if they do argue. Good to see them back. The acting was very good.
