Always the same questions for Detective Chief Inspector Isaac Cook - Why was Marcus Matthews in that room? And why did he share a bottle of wine with his killer?

It wasn't as if the man had amounted to much in life, apart from the fact that he was the son-in-law of a notorious gangster, the father of the man's grandchildren.

Yet, one thing that Hamish McIntyre, feared in London for his violence, rated above anything else, it was his family, especially Samantha, his daughter; although he had never cared for Marcus, her husband.

And then Marcus disappears, only for his body to be found six years later by a couple of young boys who decide that exploring an abandoned house is preferable to school.
