"In a spy-versus-spy thrilling high-stakes chase, Florence faces the impossible to outsmart Germany’s most brutal agent. It's New Year’s Day 1940, and snow-covered Europe is in the grip of a harsh winter. A German spy, whose face is bandaged from reconstructive surgery, parachutes into southern England to impersonate the one man who holds the key to Britain winning the war. Only Florence can stop him, but her deadliest rival is the one enemy she cannot see."
