The Dangerous Edge

This novel begins with Germany's surrender in 1945, when Erich Keller became a prisoner of war. British Intelligence then recruited him to be part of a line-crossing operation into the Soviet-occupied zone of Germany. Some 50 years later, a young British officer is ordered to trace Keller and the men who were recruited with him. "A story of conscience, of betrayals, and ultimately, a story about moral decisions and their implications."
