The CIA’s Erika Lehmann and several of her Shield Maiden cohorts return for another hold-onto-your-seat mission, this one set in 1951 in Washington, D.C. Their job is to uncover a mole at the Pentagon. Returning readers will be reunited with several unforgettable characters from past novels. Yet, with all of Whicker’s books, reading the series in order is not necessary. The author does a superlative job of filling us in with brief backstories of the other characters. The story moves along with no downtime chapters. Everything counts and makes you want to keep reading, which is a Whicker forte. Highly recommended for lovers of the thriller or espionage genres.-Joseph TempletonSun Valley Review
