For almost half a lifetime ex-agent Richard Gardiner has buried his searing memories of treachery and torture, of that nightmare time in the bloody cellars of the Gestapo and the hideous sick double-cross that followed when freedom appeared to be within his grasp.

Now 1944 seems a long time ago. Until skilled manipulators, playing on the horrors of Gardiner's wartime experience, squeeze the trigger that lies deep within him. Turning him into a merciless killing machine: hunter, and hunted, in a tangled web of retribution and death that is to decimate a whole branch of British Intelligence.

The killing-ground is among old friends and enemies. The search is for the man who always betrayed and murdered by proxy. The man known as WOLF.
