The beloved Sergeant Cribb series by Peter Lovesey
The spiritualist movement has captivated a segment of Victorian London: manifestations, the occult, and 'sensitives' are in vogue. Unfortunately, those ready to believe are vunerable to fraud.
When seance sites become targets for theft, Sergeant Cribb and Constable Thackeray are on the case. But then someone murders the medium, and the two find themselves rubbing shoulders with some rather eccentric suspects.
