A husband and wife are discovered imprisoned in their own home near Brockwell Park in South London.

The case is turned on its head, and confusion is added when bite marks on the boy's shoulder do not match Alek's dental pattern.

He gets very close to discovering that his brother is still alive, having suffered brain damage at the hands of a child molester.

He was a member of a paedophile ring, who groomed children for abuse by adults and made child pornography videos.
