Squeaky Clean

Half the Glasgow polis think DI Alison McCoist is bent. The other half just think she's a fuck-up.
No one thinks very much at all about carwash employee Davey Burnet, until one day he takes the wrong customer's motor for a ride.
One kidnapping later, he and the carwash are officially part of Glasgow's criminal underworld, working for a psychopath who enjoys playing games like ‘Keep Yer Kneecaps' with any poor bastard who crosses him.
Can Davey escape from the gang's clutches with his kneecaps and life intact? Perhaps this polis Ally McCoist who keeps nosing around the carwash could help. That's if she doesn't get herself killed first.
