Cardinal

In the frozen depths of the Canadian winter, Cardinal and Delorme are called in to deal with a missing person report - the husband of a local politician has failed to return home.

The kidnapper strikes again - and this time the choice of victim is particularly cruel. Delorme announces that she has accepted a transfer offer but will stay until the case is closed.

When a new victim is found, the murderer's intentions become increasingly clear. Meanwhile, John and Liz grow closer as they focus on the case.

Another abduction hits painfully close to home for Lise, as she and John race against time to save the next victim before it is too late.

With Josh's father is still in danger, Lise races to get to him in time. As the killer's motives become clearer, the detectives travel to Toronto to search his abandoned flat.

Cardinal and Delorme try to extract enough information from a suspect to get a lead on the killer, as he makes off into the depths of the forest with his last two chosen victims.
