Breaking the Thomas Malone case was an achievement, but nothing can prepare DC Angela Murphy and her colleagues for the challenge ahead. Escaped psychopath John Baptiste is big, powerful and out of control.

Guided by his perverse religious interpretation of morality, he wreaks havoc. As an under-resourced police department struggles to cope with the pressure of the new case, they also have to deal with the ruthless antics of ganglord Jackie McGeachy.

Pressure mounts, along with the body count... and Glasgow has never felt more dangerous.
