Some people would give their all to live another year. To live another hundred, some would destroy everything. Jim Evans, retired super-rich trader, only wants to do good. He wants to fund research that will save lives. Professor Christopher Cardini has developed medical technology he says will change the world. Through cell therapy, he can even rejuvenate the dying. Yet there's something Jim will find even all his money can't buy: protection from a brilliant, but twisted, mind. The First Horseman is the fourth in the acclaimed "Jim Evans" thriller series, by Clem Chambers. It focuses on what might happen if we had the ability to turn the human body clock back.
