“... Dyer brings a fresh setting to a familiar historical period: Readers likely don’t think immediately of Sweden when the subject is WWII. The novel’s narrative is well-balanced between talk and action, and Dyer’s crisp prose moves the story along at a brisk clip. Eve, in particular, is an intriguing character, and history buffs will enjoy seeing historical figures, including Ian Fleming and Alan Turing, make appearances . . . The Ultra Betrayal offers much to enjoy for fans of historical espionage.”
