England, 1942. The Nazis' relentless Blitz may have paused, but London's nightly blackouts continue. Now, under the cover of darkness, a madman is brutally killing and mutilating young women in eerie and exact re-creations of Jack the Ripper's crimes. What's more, he's targeting women who are reporting for duty to be Winston Churchill's spies and saboteurs abroad. The officers at MI-5 quickly realize they need the help of special agent Maggie Hope to find the killer dubbed 'the Blackout Beast.' A trap is set. But once the murderer has his sights on Maggie, not even Buckingham Palace can protect the resourceful spy from her fate.
