NEW YORK - Amanda Knox, the American former college student cleared of murder in October by an Italian court, has sold her memoir to HarperCollins, a spokeswoman for the publishing house said on Thursday.

The HarperCollins spokeswoman declined to comment on financial terms of the deal or elaborate on plans for the book, saying further details would be released in a statement on Friday.

Representatives for Knox, a 24-year-old former University of Washington student convicted of murder while studying in Perugia, Italy, said she would have no comment.

A source familiar with the deal said Knox would tell her story in the memoir, including details of the sensational case and her imprisonment in Italy.

The book deal follows a bidding war between US publishers over rights to any memoir written by Knox with a price tag expected to be well over a million dollars, according to book industry insiders. The memoir was considered a hot property because the world has yet to hear all the details from Knox, who was found guilty in 2009 of murdering her 21-year-old British housemate, Meredith Kercher, and spent four years in prison. An Italian court in overturned Knox’s conviction in October. Also cleared was her boyfriend, Rafaele Sollecito, leaving Ivorian drifter Rudy Guede as the only person convicted in a killing investigators believe was carried out by more than one person.
