There’s a rapist prowling Aberdeen’s streets, leaving a string of tortured women behind. But while DS Logan McRae’s girlfriend is out acting as bait, he’s dealing with the blood-drenched body of an unidentified male, dumped outside A&E. When a stash of explicit films turns up, all featuring the victim, it looks as if someone in the local bondage community has developed a taste for violent death, and Logan gets dragged into the twilight world of pornographers, sex-shops and S&M. With MacBride’s gritty sense of place and trademark gallows humour, this is a gripping third outing for DS McRae.
