I have read all Georgette Heyer's Regency Romance books more than once, but this the first mystery I have read of hers. I REALLY ENJOYED THIS BOOK. The same method of writing as in the romance books. I recognized the similar characterized in the book. I knew the guilty party almost at once. It was similar to mysteries of that time. It reminded me of a lock room story. The characters are all there, the damsel in distress, the stern husband, the sister who is amusing, the silly nephew, the butler, and the cook. Superintendent Hannasyde and Sergeant Hemingway are called to a home and find the homeowner dead by a blunt object. The timeline shows no one has time to do the murder. After some silly actions by the characters, Inspector Hannasyde knows the answer. This is the fourth book in the series. I highly recommend this book and series.
