Barnett is known for brokering book deals of some of the world's most prominent people. He has represented Barack Obama, Bill Clinton, George W. Bush, Tony Blair, Queen Noor of Jordan, and Pakistan's Benazir Bhutto.
Knox is a different character. She was a college student accused of murdering her roommate at an Italian study abroad program with the help of her Italian boyfriend. The sensational case, which the Italian courts contended was a sex game gone wrong, attracted international media attention. In 2009, Knox was convicted in the killing of Meredith Kercher; this year the verdict was overturned.
Barnett's law firm, Williams & Connolly, will "represent [Knox] in discussions with various book publishers who have expressed an interest in Amanda writing a book," according to a statement.
In October, we asked readers to vote on whether they thought Knox should get a book deal. More than 800 said she should – and almost 48% of all voters in our poll said they believed Knox to be innocent.
