London, 1942. Charlotte Fenimore is back home on a week's leave from the Women's Auxiliary Airforce. She had planned for a week of rest and recuperation. She hadn't planned to fall deeply in love with an irascible detective called Dan Chalmers, a wounded hero of Dunkirk who believed no woman would ever look at him again. DI Chalmers is in London to arrest a gang of dangerous East End criminals and root out corrupt police detectives at the Met -- and his involvement with Charlotte brings her into serious danger. And then the plane flying Charlotte to the wilds of Scotland comes down in a storm... In a time of war, with danger around every corner, how can their relationship survive?
