From the author of The Perfect Place to Die and Don't Go to Sleep comes another chilling historical mystery. Seventeen-year-old Mary Churchill feels helpless as London is ravaged by air raids and mandatory blackouts. As the youngest daughter of the Prime Minister, she longs to do something important, to help those in less fortunate circumstances. On a night out on the town, she connects with an older woman who is in-between jobs and promises to meet her again the next day. Except she never shows up. Mary has a sense that something is wrong, so she decides to go searching--and finds her brutally murdered. Horrified, Mary immediately goes to the police.
