Dr Neil Mackenzie's life was boring - well what do you expect if you teach maths and live in Tunbridge Wells? That is until one of his old students needed his help. It wasn't a tricky equation she couldn't do either - no, Grace wanted him to help her steal back the £50,000 Marc Gilbert had defrauded from her mother. And if that wasn't enough there was Reina, the Greek waitress he couldn't quite forget and Sasha, Gilbert's sexy girlfriend from the gym to keep him on his toes. Not to mention Rocky and Gere, badminton buddies who lend a hand and a few laughs as he finds himself becoming more like his boyhood hero Philip Marlowe than maths boffin.
