The stately homes of England are under threat from the seemingly untouchable jewel-thief 'Creeping Jenny'. After the latest burglary, Inspector Baddeley suspects the country-house home of Henry Mordaunt might be the next target. Mordaunt is hosting a party to celebrate the engagement of his daughter, when her fiancé intends to hand over a priceless gem as a gift. But murder unexpectedly strikes, and Mordaunt relies on Baddeley to unmask the culprit. Can he cope without the help of super-sleuth Anthony Bathurst, and his redoubtable sidekick Peter Daventry? was originally published in 1929. This new edition includes an introduction by crime fiction historian Steve Barge.
