?A stunning spy story... incomparable.? ? The Guardian

It's 1979, and a group of former SS officers are devising a plan to seize power in West Germany. XPD is a brilliant novel constructed around a supposition that Churchill secretly met with Hitler in 1940 to discuss terms of a British surrender. British agent Boyd Stuart is intent on preventing those wartime documents from becoming public. XPD ? short for ?expedient demise,? the code used by the Secret Intelligence Service to refer to the assassinations it carries out ? is another stunning novel from Len Deighton.
