As a storyteller, McEwan has few equals. From the novel’s opening lines—“My name is Serena Frome (rhymes with plume) and almost forty years ago I was sent on a secret mission for the British Security Service”—he draws us into the dreary world of Cold War England, circa 1974,  time of internal social and political upheaval. The story purrs along like a well-oiled machine, as Serena falls in love with Tony Canning, a married professor and much older man. The affair ends badly, though not before Canning has set her on an eventful career path with MI5.
