Take a good hard look through your pantry. Are all your cans of vegetables there? Your cereal boxes? Have you counted them? Is everything where it should be? If it is, then breathe a sigh of relief -- you have not been visited by Martin yet.
Who is Martin? Until recently, he has been a sort of obsessive compulsive thief who lives off of a series of "clients." Calling himself a career criminal, the star of this fun book would rather steal a can of beans than any cash to avoid being noticed. While he isn't an anti-hero, he isn't a parasite either. If you are one of his clients, count yourself lucky -- he'd more than put his life on the line for you.
However, go and recount your groceries to make sure that there isn't Something
Missing.
