For Glasgow – with love and squalor: The Second Cut, by Louise Welsh, reviewed

Never, never kill the dog. It’s rule one in the crime writer’s manual. Cats are bad enough, as I can testify, having once had the temerity to behead a cat — in a novel, I mean —and then crucify the mutilated corpse upside down on a church door. As a general rule, if you kill a domestic pet in your crime story you should expect a hostile postbag of epic proportions.
