Just Another Sucker — James Hadley Chase

A man will do almost anything when a rich and beautiful woman offers him fifty thousand dollars just to make a telephone call. But when that telephone call is part of a fake kidnap plan to extract five hundred thousand dollars from one of the richest men in the world, only a sucker would gamble on the deal paying off in his favour. Harry Barber is a sucker. After three and a half years in jail for a crime he didn't commit, with no job and no money, he is the perfect target of a brilliant plan to frame him for the brutal murder of a young girl.
