It's this bloody case"" which is keeping the C.I.D.'s Saltfleet awake and bloody it is with Colin Wilson's penchant for criminosexual horribilia and the clinical mot juste (try intracrural intercourse for starters) having to do with the schoolgirl who is raped and strangled with a telephone cord only it turns out she's a call girl for a pervert called Lytton who is found dead and nude on a black pile rug. The plot is basic enough but of course it's tufted with fetishism, black magic, et dreadful alia. The only filing you really have to think about is that the king of kink plans to write eleven more in this series.—Kirkus

Wilson's second crime novel to feature Gregory Saltfleet.
