The brutal murder of a lottery winner has Castle and Beckett up to their eyeballs in suspects, envious and angered by the victim's sudden move from the poorhouse to the penthouse. As the precinct buzzes with fantasies of what our cops would do if they won the lottery, Martha struggles with the reality of such a decision when she suddenly inherits money she feels she doesn't deserve.

There are two kinds of folks who sit around thinking about how to kill people. Psychopaths and mystery writers. I'm the kind that pays better. Who am I? I'm Rick Castle. Every writer needs inspiration. And I found mine. And thanks to my friendship with the mayor, I get to follow her around. And together we catch killers.
