Not A Penny More Not A Penny Less by Jeffrey Archer

One million dollars – that's what Harvey Metcalfe, lifelong king of shady deals, has pulled off with empty promises of an oil bonanza and instant riches. Overnight, four men – the heir to an earldom, a Harley Street doctor, a Bond Street art dealer and an Oxford don – find themselves penniless. But this time Harvey has swindled the wrong men. They band together and shadow him from the casinos of Monte Carlo to the high-stakes windows at Ascot and the hallowed lawns of Oxford.
