London is alive with the sound of shadows.

When Tommy Nolan was sent abroad to avoid being made a saint too soon, he thought he'd be a glorified tourist. But when an impossible prehistoric artifact the Vatican is looking at is stolen from the British Museum, they do the first thing that comes to mind -- they call the cops.

But Tommy is soon convinced that the artifact is more than it seems. The crime scene looks like a war zone. The owners of the stolen merchandise eye him with suspicion. His new partner has a shady, mysterious past. The police are ready to arrest him. The city itself seems primed to explode.

Worst of all, the darkness itself is closing in on Tommy, the city, and everyone who lives there.

But Tommy isn't one to curse the darkness. The darkness curses him.
