The stakes are high, for the survival of the British campaign in North Africa is in the balance. He arrives suddenly in Cairo from out of the desert, armed with a radio set, a lethal blade and a copy of Daphne du Maurier’s Rebecca – a ruthless man with a burning, relentless conviction that he will win at all costs. He is known to the Germans as ‘Sphinx’, to others as Alex Wolff, a European businessman. ‘Our spy in Cairo is the greatest hero of them all…’ (Field Marshal Erwin Rommel, September 1942) The Key to Rebecca is a gripping thriller set during the Second World War, from the author of Eye of the Needle, Ken Follett.
