You're Dead Without Money — James Hadley Chase

Joey Luck and his daughter Cindy are small-time criminals going nowhere fast, until they join forces with Vin Pinna, a hardened criminal on the run from Miami. They soon begin to set their sights higher and turn their hands to kidnapping. But their hostage, ex-movie star Don Elliot, seems to have different ideas. When he wants in they form a 'quartet in crime', and this time the stakes are higher still - eight Russian stamps worth a million dollars. 'Realistic and suspenseful far beyond his average' Observer
