This is my second KF book, following on from "Eye of the Needle" (which was an audio book). While Eye of the Needle was about a German spy in London in WWII and the British intelligence officer's attempts to catch him, "The Key to Rebecca" is about, er, a German spy in Cairo in WWII and a British intelligence officer's attempts to catch him. Same story, different setting? No, not at all, fortunately. Although the two novels have similar themes, KF makes the most of the different setting, with the reader feeling the heat and tasting the sand as Vandam, the British intelligence officer, has to cope with local hostility and an incompetent superior while struggling to capture the clever, ruthless and very slippery German agent, Wolff. Again, KF gives the story a human angle, with Vandam a widower with a son to bring up; Wolff's old flame Sonja, a depraved belly dancer who despises the English; and Elene, a beautiful young Jewish woman who hopes Vandam will help her escape from her dependency on affairs with wealthy older men. Each is destined to have an influence on the war in the desert as Rommel strives to crush the Allied forces in Egypt. KF writes in an engaging, easy to read style, which encourages the reader to fly through the pages, desperate to discover whether Vamdam will ever get the better of Wolff, who always seems to have a trick up his sleeve. Not quite as good as Eye of the Needle, and probably more of a 3.5 stars, but too enjoyable to knock it down to 3 stars. Next!
