The Looking Glass War  (English, Paperback, le Carre John)

When the Department - faded since the war and busy only with bureaucratic battles - hears rumours of a missile base near the West German border, it seems the perfect opportunity to regain some standing in the Intelligence world. Desperate for glory and determined to outdo their rivals at the Circus, including George Smiley, they send deactivated agent Fred Leiser back into East Germany, armed only with some schoolboy training and his memories of the war. In the land of eloquent silence that is Communist East Germany, Leiser's fate is no longer his own.

Showing men carried away by fear and pride, The Looking Glass War is a powerful, moving story of human frailty.
