Bruce Robertson is a Detective Sergeant in Edinburgh, Scotland who suffers from Borderline personality disorder; He is a scheming, manipulative, misanthropic man who spends his time indulging in drugs, alcohol, sexually abusive relationships, and "the games" — his euphemism for the myriad foul plots he hatches directed at workmates. Robertson also delights in systematically bullying and taking advantage of his mild-mannered friend Clifford Blades, a member of Robertson's masonic lodge whose wife, Bunty, he repeatedly prank calls and asks for phone sex.
