Four Kinds of Rain - Robert Ward

Broke, recently divorced, and a total deadbeat, Bob Wells has spent his life as a psychiatrist only doing good in the world. When one of his patients with clear paranoid delusions starts to lose a grip, Bob has no choice but to intervene. Emile Bardan is haunted by demons, and he believes that someone is trying to steal his most prized possesion, the legendeary Mask of Utu. Bob thinks it's all part of Emile's imagination until he discovers that Emile is telling the truth and that the mask is worth millions. It's Bob who may actually be the one losing his grip. He's tired of helping people for nothing, tired of being treated like dirt—and while he may have met the girl of his dreams, he doesn't want to lose her because he can't take care of her. There is only one thing to do: Bob is going to steal the mask himself: But doing so may mean making the biggest mistake of all—as he proceeds down a path into a dark abyss from which there is no return.
