Chase James Hadley. An Ace Up My Sleeve

An Ace Up My Sleeve' is a story of blackmail.
It's a story of three people, all out for one thing : all determined to do anything to get it.
It's a story of bluff and counter-bluff, a game which develops into a deadly battle of violence and extortion.
From the moment Helga Rolfe, the elegant wife of one of the richest of tycoons, picks up a gum-chewing boy, young enough to be her son, events jump, bank and skid through a series of 180 degree turns and hair-raising gambits, racing to a climax of shattering impact, for both winners and losers.
