A Pinch of Snuff (Dalziel & Pascoe, #5)

Love, or at least pornography, are for sale at the arty Calliope Kinema Club on posh, proper Wilkinson Square. According to Yorkshire police superintendent Dalziel, it's all legal. Detective Peter Pascoe, however, doesn't believe it. His dentist, who knows real broken teeth and blood when he sees them, insists that the pretty actress wasn't playing a part when it happened. But the action that  puts Pascoe into the picture is homicide. The sudden death of the Calliope's proprietor soon turns a sleazy sex flick into serious police business. And now Dalziel and Pascoe are looking into the all-too-human desire for pain, pleasure...and murder.
