Ms. Atkinson has written an attractive spy thriller and mystery, set in 1940 and 1951. Given Atkinson’s past books, then it is no surprise that the story unfolds in a non-linear format. Juliet is recruited to MI5, and the resulting story is very English with regular tea providing comfort and solace to characters named Peregrine and Prendergast. Much like George Smiley in the legendary Le Carre novels, people in Atkinson’s story appear normal and ordinary, but nothing will be as it seems. This is a very entertaining book with some well-timed plot twists.
