File photo of Amanda Knox during trial  in Perugia
Amanda Knox, the U.S. student convicted of killing her British flatmate in Italy three years ago, sits in the courtroom after a break during a trial session in Perugia in this March 12, 2011 file photo. Amanda Knox, the American woman cleared of murder in October by an Italian court, has sold her memoir to Harper Collins, a spokeswoman for the publishing house said on February 16, 2012. A bidding war broke out between U.S. publishers over the rights to any memoir written by Knox with a price tag tipped at around one million dollars, according to book industry insiders.
