At the Villa Rose

At the Villa Rose is a detective novel by British writer A.E.W. Mason featuring his character Inspector Hanaud. In Aix les Bains during the early 20th century, Celia Harland, a beautiful (of course) young English girl down on her luck is befriended by a rich widow, Madame Dauvray, an addict of "spiritualism", and stages seances for her benefactrix, while knowing full well that the supposed manifestations from the spirit world are entirely bogus. This set-up supplies the opportunity for a criminal gang master-minded by Madame Dauvray's maid, with their eyes on the widow's jewellery collection, to engineer an introduction for one of their number, Adele Tacé ("Rossignol") whose taunts of disbelief goad the old lady into allowing a seance to be held which, unsuspected by either Celia or her patron, will be the cover for murder and robbery. The crux of the plot is that Celia, as medium, will be made their innocent victim, on whom suspicion is to be planted.
