Waking the Dead

Boyd is finding it hard to find a replacement for Mel and so, in the meantime, DS Andrea Stephenson is drafted into the team.

The team are finding it extremely hard to come to terms with Mel's death, and finding a replacement is proving to be a heartbreaking challenge.

Ex-cop Eddie Vine mysteriously invites Boyd to visit him in prison, where he is serving life for murdering his partner and best friend, Tom Pallisser.

Boyd is tormented by the possibility that he has made a grave error, and is forced to delve into his past and examine his conscience.

A millionaire businessman is found dead one year after he disappeared.

The team discover that the motive for the murders was to prevent the truth of the killer's secret life from reaching his wife.

Grace is called to give evidence at the appeal of Tony Green, whose arrest and conviction thirty years earlier was her first case.

The team finally get a break when they trace the killer through Green's former cell mate, who turns out to be one of Grace's fellow professionals.

The team are convinced that a man about to be released from prison is actually a killer, but they need the evidence to prove it.

The team fails to amass enough evidence to link Hunt to the killings ahead of his release, so Boyd has him followed as a pre-emptive measure.

New DNA results reveal that the man who was convicted of murdering two anti-nuclear campaigners in the 1980s wasn't the real killer.

The anti-terrorist squad has Boyd's HQ under lock-down, and the team is quarantined until the substance that affected Felix can be identified.
