ÖZET
As Sally Wainwright's drama continues, Catherine is still deeply troubled by her colleague's death - and even more shocked to learn the killer ran over the victim numerous times. Who could commit such a cold-blooded act? Desperate to find Tommy, she visits his mother Lynn, an addict who appears to be in a state of confusion. But then the woman takes the sergeant by surprise, asking a question about her grandson Ryan - something she couldn't possibly have known. James Norton and Caroline O'Neill co-star.
