Staid, celibate linguistics professor Anthony Ponton, grudgingly fulfilling his role as guardian to his nephew Eric, tracks him to sleazy stripper-clubs in London's Soho district-- where the young man's obsession with Vicky marks him as a possible suspect when she becomes the second stripper to be killed. Did Eric, clearly a nutter, do it? Or did the two women die because of a spot of blackmail they were trying out on a ``Mr. X''? Anthony and his unlikely chum, raunchy stripper and mental lightweight Sylvia, try to puzzle it through and manage to scare off the rotter making an attempt on another club artist, Carla, also trying her hand at a bit of blackmail--on Anthony's university colleague David. Eventually, Anthony realizes that one murder was intentional, the other an accident--but will his conscience and moral priggishness also demand legal punishment for the latter? Offbeat--if not quite likable--characters almost make up for some hokey plot twists, but Gilpin's (Is Anybody There?--not reviewed) insights into the stripper-world are dead-on.
