White Rain. The Misadventures of Max Bowman, #4

For almost a year, Max Bowman has been locked away in the Community - a "retirement" home for former CIA spooks with secrets too scary to share with the world, where the residents are drugged into obliviousness and kept content with reruns of Bonanza and The Beverly Hillbillies. But then after a daring escape, Max is back - or, at least, what's left of him. He's lost his love, his home, his money and most of his memories.
And the only way to get any of them back is by taking on a crooked lobbyist whose menace is almost as big as his stomach. This creep is selling white supremacy - and his ancient donors are more than willing to dive into that particular gene pool. Max is truly on the highway to hell - with Mar-a-Lago serving as a rest stop along the way.
