In the year since arriving in London, journalist Ruth Brown has put a face on the war for her readers at home in the U.S. Thus far, juggling her career and her relationship with Detective Inspector Trevor Gelson hasn't proven too challenging. The war gets personal for Ruth when her friend Amelia is murdered, and Trevor is assigned to the case.

Life gets even more unsettling when clues indicate her best friend, Varis, is passing secrets to the enemy. Convinced Varis is innocent, Ruth must find the real traitor as the clock ticks down toward Operation Husky-the Allied invasion of Sicily. Circumstantial evidence leads Trevor to suspect her of having a part in Amelia's death, and Ruth must choose between her heart and her duty.
