The governor's wife - Michael T. Harvey

It's been two years since disgraced Illinois governor Ray Perry disappeared from a federal courthouse in Chicago moments after being sentenced to thirty-eight years in prison on corruption charges. PI Michael Kelly is sitting in his office when he gets an anonymous email offering to pay him nearly a quarter million dollars if he will find Perry, no questions asked. Kelly's investigation begins with the woman Ray Perry left behind - his wife, Marie. Ostracized by her former friends and hounded by the feds, Marie tells Kelly she has no idea where her husband is. Like everyone else, Kelly doesn't believe her. As he hunts for her husband, Kelly begins to unwind Marie Perry's past.
What he finds is a woman who turns out to be even more intriguing than her husband, with her own deeply complicated reasons for standing by him.
Everyone in Chicago has secrets, including the governor's wife. Some of them she shared with her husband. Some of them she kept to herself. And some of them could get Michael Kelly killed.
The Governor's Wife is a hard-eyed look at the intersection of the political and the personal, at the perils of trusting even those closest to us and the collateral damage of our highest aspirations. This is stylish, knock-out suspense from a modern master.
