Cat - as in burglar (the misadventures of a housebreaker)

Twenty-year-old Marty does a bit of housebreaking to make ends meet. He thinks all his Christmases have arrived together when he finds a kitbag stuffed with cash and assumes it's tax evasion, so unlikely to be reported to police. Unfortunately, it is actually money-laundering for a tough East End gang and they are searching for the money. He wants to return it anonymously but things don't go easily to plan.
