Doyle has tracked terrorists across three countries. He's never followed a trail that leads somewhere this old — or this impossible.

The conspiracy runs from London to Ireland to France, funded by someone Doyle can't identify and protected by people who should know better. But it's where the trail ends that stops him cold: a stained-glass window in a centuries-old killer's home — one that supposedly holds the secret to immortality.

One man will do anything to possess it. What Doyle finds when he confronts that man shatters the boundary between the thriller he thought he was in and something far darker.

Hutson collides modern terrorism with medieval evil and makes it feel inevitable — because by the time the impossible becomes undeniable, you're already too deep in to look away.

“Britain's greatest living horror author.” — Dark Side

“An expert in the art of keeping the reader turning the pages.” — Time Out

The living will envy the dead before this one is done.
