How much blood would you spill to avenge those you love? What if you're a blithe haemophobic psychopathic ex-con from Edinburgh? Andy Park thinks he's discovered a way to make a care worker pay for his ill-treatment of Park's brain-damaged wife, Liz. But Park isn't prepared for the fall-out. Because in Park's world, when things go wrong, they go spectacularly wrong. Before long, Park's teenage son is in mortal danger, his daughter and her fiance are cutting up corpses, and Old Mrs Yardie's country cottage has been requisitioned for the purposes of kidnapping an erstwhile tobacco smuggler. And yet Park's world is a bed of roses in comparison to Tommy Savage's. Savage is being blackmailed by a masked man known only as Mr Smith - for what, he has no idea. A near-fatal accident in an abandoned apartment results in Tommy and his brother, Phil, heading to a graveyard with only a couple of swords and a bag of cash for company. Will they survive the night? Will anyone?
