Two men enter Rosie McKechnie's home, bind her, and make a precise three  inch cut on her back. They mention the name Barbara, which means  nothing to Rosie but has significance to her husband Brian, who has good  reason to keep Barbara's existence a secret from Rosie. Brian is soon  being blackmailed and when the police prove to be useless, he turns to  Nick Duffy, a former vice officer who is a bit touchy about his reason  for leaving that job.
Duffy spends quite a bit of time trolling  the sleazy side of Soho, an area he got to know well when he was working  vice. His investigation takes him to peep shows and massage parlors and  places that show dirty movies (this is before video rentals and the  internet put X-rated theaters out of business). A few chapters explore  Duffy's diverse sexual interests and his frustratingly impotent  relationship with the woman in his life. There aren't many bisexual  detectives in mainstream crime fiction (at least, not that I've seen)  and Duffy offers an interesting perspective on such issues as the  difference between one night stands with men and women.
With  crooked cops, gangsters, and the denizens of Soho's underbelly, Dan  Kavanagh (the pen name used by Julian Barnes) provides a colorful cast of unsavory characters to enliven  Duffy's life -- although it is exactly the sort of life in which Duffy  wants to wallow. The sharply written story moves quickly and reaches a  satisfying resolution. This novel (and presumably the short series)  would not be a good fit for cozy mystery fans, but readers who like  their detective fiction served with a side order of raunchiness should  enjoy it.
