Eighteen months on from the case that nearly cost him his life, only DCI Jamie Carver knows the incredible extent of the Worshipper Killer's network of depravity - and the storm that will hit when others learn of it. They include those who walk Whitehall's corridors of power, as well as others in high office, and even, maybe, the upper echelons of the Police Service itself. When former members of that network start dying, Carver suspects that someone is out to make sure that their involvement at least, remains hidden -and will stop at nothing to do so. Needing information, fast, but right now chained to a desk, his only recourse is the person who, after last time, he vowed to never have contact with again - the extraordinary and dangerously-seductive dominatrix, Megan Crane.
