The proposal that agent Liz Darhansoff has been shopping on the rise and fall of Eliot Spitzer has found a home. After PWreported last week that the book-to-be, by Fortune magazine (and Smartest Guys in the Room) writer Peter Elkind, was starting off at a base price of $350,000, expected winner Portfolio has closed the deal.

The Penguin imprint acquired world rights from Darhansoff, of Verrill & Feldman. Elkind is collaborating on the book with documentary filmmaker Alex Gibney (Taxi to the Dark Side); Gibney is working concurrently on a documentary about Spitzer. (Gibney and Elkind worked together on the film adaptation of Smartest Guys in the Room.) No pub date yet.
