November 1919. A relaxing few weeks by the seaside with her husband, Sidney, could almost convince Verity Kent that life has returned to the pleasant rhythm of pre-war days. Then Verity's beloved Great-Aunt Ilse lands on their doorstep. After years in war-ravaged Germany, Ilse has returned to England to repair her fragile health -- and to escape trouble. Someone has been sending her anonymous threats, and Verity's Secret Service contacts can only provide unsettling answers.
