I found this to be very funny with two very likeable main characters, despite the fact that they were unrepentant criminals!
Bex and his best mate, Ollie, make their living carrying out jobs. Big jobs, little jobs, usually to order, but sometimes simply taking advantage of what is available. Ollie is shown as the "nice but dim" character, while Bex regularly comes up against the old Bill, and usually comes out on top.
Yes, they are the bad guys, but they are likeable rogues, with a cast of supporting characters who are brilliant foils to their crimes.
I wasn't aware when I first read this that it had been made into a TV series - I wish I'd seen it! Very funny, and a perfect antidote on a long bus journey...once you get past the fact that these are the law-breakers!
