The heatwave continues and so does DI Will Wagstaffe's investigation into the horrendous murders of unconvicted paedophiles.

The team investigate the death of a young nurse on the Underground. CCTV reveals the victim fleeing an invisible assailant, but forensics find a DNA link that changes everything.

As the team delves deeper into the mysterious poisonings, Staffe suspects that whoever is behind the attempts to cover up the supply chain has a powerful influence.

A young woman is found murdered in an East London church and Staffe must establish if the culprit is her stalker or if the answer lies in her tumultuous personal life.

A prime suspect in the Suzy Moyland case is found dead in the same East London church and Staffe finds himself at a crossroads.
