What's the best way to purge an unfaithful husband? Become a spy for British Intelligence, of course.

Desperate to get out of London, and determined to help the war effort and stop thinking about her philandering husband, Fiona Figg volunteers to go undercover.

At Ravenswick Abbey a charming South African war correspondent has tongues wagging. His friends say he's a crack huntsman. The War Office is convinced he's a traitor. Fiona thinks he's a pompous prig.

What sort of name is Fredrick Fredricks anyway? Too bad Fiona doesn't own a Wolseley pith helmet.

At Ravenswick a murderer is on the prowl, and it's not just the big-game hunter who's ready to pounce.
