It is 1919, and the War to End All Wars has been won. But for Scotland Yard Inspector Ian Rutledge, recently returned from the battlefields of France, there is no peace. Suffering from shell shock, he plunges into his work to save his sanity. But his first assignment is a case certain to spell both personal and professional disaster. A popular colonel has been murdered in Warwickshire, and the main suspect is a decorated war hero. No matter what the outcome, Rutledge may not escape with his career intact. And, win or lose, the cost could be even higher: The one witness who could break the case is himself a shell-shock victim. In this war-ravaged man, Rutledge sees his own possible future, should he fail.
