It is 1917, and the United States is still wavering on the brink of war. At an elite intelligence meeting at a Hyde Park mansion, Kit's handlers pair him up with someone he would never have expected-his mother. There's a German mole somewhere in the British government, and the most likely suspect happens to be a diehard fan of the famous American theater actress Isabel Cobb. Disguised as a German-American reporter named Joseph William Hunter, Kit follows his mother and her escort Sir Albert Stockman from the relative safety of London into the lion's den of Berlin.This third installment in Butler's critically-acclaimed series features the swash-buckling action, charismatic leading man, and artful prose that have won the hearts of historical crime fiction fans everywhere.
