When the body of a young man is discovered in a derelict building, Detective Chief Inspector (DCI) Cassie Stuart is called in to investigate with her partner, Detective Sergeant (DS) Sunil "Sunny" Khan (Sanjeev Bhaskar). Jimmy Sullivan was a homeless runaway away boy, murdered in 1976 when the building was a hostel. His diary implicates four suspects; a clergyman, an eminent entrepreneur, a community worker, and a disabled house-bound husband caring for his wife. Each has a secret to hide. As their lies unravel, the people they love most begin to wonder what else they might be capable of. Nothing in this case is black and white. Can you ever really know the people closest to you? What secrets have they buried?.

Since the car was stolen, the car key, which was original, should still have been in the possession of the first owner. It couldn't have been found underneath the body. Except if the key was stolen first, or the key was left in the car, either in the ignition or above the windshield shade, under the mat, etc., and since that was never established, not a plot hole.

User Reviews

This is really very well watching. It's captivating
3 November 2015 | by jonnithomasSee all my reviews

yes, it's a murder and a 'whodunit' but it is so much more than that.

the characters are well directed and acted and feel totally believable. the detective work builds as the story unfolds and leaves you wanting to know what happens next.

it's not like any wam bam cop story from the US which may not be to everyone's taste. it's just far more realistic and solid with each character 3d. there's some humour and some sadness and lots of realism. the characters are real people, they don't have ridiculous hair, teeth and smiles or know things in a semi mystical way. they work it out and have hangovers and sometimes cry. You know, like real life.

I thoroughly recommend that you watch this.
