A brilliant codebreaker, top of her graduate class, Maggie Hope is nonetheless relegated to secretarial duties in wartime London. But her assignment is No. 10 Downing Street, where working for Winston Churchill affords Maggie access to the highest levels of government—and a chance to use her talents for the Allied cause. Susan Elia MacNeal's Barry Award-winning historical series (further nominated for Agatha, Macavity, and Edgar Awards) is inspired by the real-life secretaries and spies who worked for Britain's SOE.

World War II rages on through 1941, but Maggie Hope has found a moment of rest on the coast of Scotland, in her riveting fourth mystery (following His Majesty's Hope). Recovering from her deadly mission in Berlin, Maggie settles down to teach at her old spy training camp, yet she is soon drawn into another web of danger and intrigue when three ballerinas fall strangely ill in Glasgow—including one of Maggie's dearest friends. She partners with MI-5 to uncover the truth behind their unusual symptoms, and exposes secrets that might put countless British lives at stake.
