Peter Grant is part of a very special London police unit. Full-time cop and part-time wizard, he works on rather unusual crimes--those that involve magic and the general weirdness that permeates London's dark underbelly.

His latest case begins with a perfectly innocent car on a homicidal killing spree--without a driver. But then, before you know it, there's a Bosnian refugee, the Most Haunted Car in England, a bunch of teenagers loaded on Ketamine and a seemingly-harmless wooden bench with the darkest of pasts...

The place is Earth. The time is the near future - all too near.
          Industrial development has accelerated out of all control, spawning dangerous new technologies and laying the planet to waste. While the inner cities collapse in guerrilla warfare, a dark age of superstition dawns.

          If Earth is to survive, somebody has to stop them. From London to New York to Turkey, Ace follows the Doctor as he prepares, finally, to strike back.
