England 1947.

Augustus Mandrell aims to commit the ultimate ‘locked room’ murder.

He assumes the identity of Louis Proferra — a one-armed agent from the International Military Tribunal — and succeeds in penetrating a subterranean military facility in order to assassinate a Nazi war criminal.

His plan is perfect . . . but even the best-laid plans can sometimes go awry.

Alarm bells ring when one of the guards finds a man bound and gagged in a car outside — with one arm. The real Louis Proferra.

They’re onto Mandrell. But the idea that any unauthorized person could penetrate to Bravo Red level is unthinkable. Impossible, even. But not to Mandrell.

The chameleon-like contract killer must use all his skills in disguise, deception and psychology to survive.

He’s found a way in. Now he must find a way out.

Fans of Len Deighton, Ian Fleming, George MacDonald Fraser and Frederick Forsyth will devour this classic spy series full of twists.

Please note this edition includes a new introduction by award-winning crime writer Mike Ripley.
