Amanda Knox agrees $4m deal for tell-all book

Amanda Knox, the American student acquitted of murdering her British room-mate in Italy, has signed a reported $4m (£2.5m) book deal for her account of the events surrounding her arrest and trial.

Ms Knox, 24, from Seattle, has not publicly discussed her ordeal beyond a brief expression of gratitude upon her release from jail in Perugia last October.

"[She] will give a full and unflinching account of the events that led to her arrest in Perugia and her struggles with the complexities of the Italian judicial system," her publisher, HarperCollins, said. "Aided by journals she kept during her imprisonment, Ms Knox will talk about her experience at the hands of the police, prison guards and inmates."

The book is tentatively scheduled for 2013. Financial terms were not disclosed for what is surely a seven-figure deal.

Jonathan Burnham, of HarperCollins, said Ms Knox would work with a collaborator. "The experience of actually sitting down in a room and talking for an hour... with Amanda made me realise this was a very mature, intelligent woman who had been through an extraordinary experience," he said.

This week, prosecutors asked Italy's highest criminal court to reinstate the murder convictions of Knox and her former boyfriend, Raffaele Sollecito, who was also acquitted. Prosecutor Giovanni Galati said he was "very convinced" the pair were responsible for stabbing to death Meredith Kercher, 21, of Coulsdon, Surrey on 1 November 2007.

A third defendant, Rudy Guede, was convicted in a separate trial of sexually assaulting and stabbing Kercher.
