During her four years in an Italian prison, Amanda Knox had to fend off unwanted sexual advances three times -- twice from male prison employees and once by a female inmate, according to The New York Times. 
 
 The Times obtained a copy of Knox's memoir, "Waiting to Be Heard," which is scheduled for release on April 30. 
 
 Knox spent years in Capanne prison awaiting trial for the 2007 murder of her British roommate, Meredith Kercher, and then while serving a 26-year prison term following her conviction. She was acquitted on appeal. 
 
 Her nearly 500-page memoir does not cover her life after prison and her most recent nightmare, the ruling in March by Italy's Supreme Court that she must be tried yet again for Kercher's murder. 
 
 Those details and more will be discussed in her exclusive television interview with ABC News anchor Diane Sawyer.

 According to the Times, Knox was in such a deep state of despair behind bars in Italy that she considered committing suicide by suffocating herself with a garbage bag. 
 
 Knox wrote in an author's note at the end of her book, "Until now I have personally never contributed to any public discussion of the case or of what happened to me, while I was incarcerated, my attention was focused on the trial and the day-to-day challenges of life in prison. Now that I am free, I've finally found myself in a position to respond to everyone's questions. This memoir is about setting the record straight."

 Knox, according to the Times, wrote about having her every move analyzed from afar -- including the video of her kissing her then-boyfriend, Raffaele Sollecito, outside the crime scene. 
 
 "First I showed not enough emotion; then I showed too much," she wrote. "It's as if any good will others had toward me was seeping out like a slow leak from a tire, without my even realizing it." 
 
 The Times described how Knox laid out her defense in detail -- writing that on the night of the murder she was at Sollecito's apartment smoking marijuana, reading a Harry Potter book out loud in German and watching the film "Amelie." 
 
 During her interrogation, she said, police sporadically slapped her on the back of her head. 
 
 Panicked and confused, when she asked to make a phone call. 
 
 "The guard looked at me like I'd asked for caviar and prosecco," she wrote. 
 
 She described her first moments of freedom after her acquittal -- writing that she was handed a touch screen Blackberry to make a call. 
 
 "I hadn't picked up a cell phone in years, and never a touch-screen," she wrote. "This device was as good as sci-fi to me."

 This story has been updated from an earlier version. ||||| In her soon-to-be released memoir, Amanda Knox will reportedly claim that she was sexually harassed by prison guards during her four years at Italy's Capanne prison. 
 
 In the book, Knox according to the Daily Mail, writes that prison guard Raffaele Argiro would summon her for "chitchats" alone in his office at night. Knox reportedly expands on letters she wrote to friends obtained by British tabloids, saying the guard was fixated on the topic of sex, asking about her partners and if she would have sex with him. 
 
 "I was so surprised and scandalized," Knox was quoted writing in the memoir, according to the Daily Mail. 
 
 Her memoir, "Waiting to Be Heard," published by HarperCollins, will be released April 30. 
 
 Argiro has since retired and denies the allegations.

 "Obviously to hit on a prisoner who has no power when you're a man who is a prison official with enormous power, is very, very scary for a young woman," Vanity Fair contributing editor Judy Bachrach said. 
 
 Knox was imprisoned at the Capanne prison in Perugia since she was arrested in 2007 for the murder of her British roommate Meredith Kercher. In 2009, Knox was sentenced to 26 years in prison while ex-boyfriend Raffaele Sollecito was sentenced to 25 years. 
 
 Knox was released from prison in 2011 after the appeals court threw out her conviction and scolded the prosecution's handling of evidence and the case. Sollecito was also released. 
 
 Knox reportedly writes about a female inmate who wanted to start a lesbian affair. Knox alleges that she was falsely told by officials that she was HIV positive.

 "Within the Italian people there is still that feeling that she's a spoiled rich kid who decided to kill her roommate for kicks. This is ludicrous. So there is a possibility she will be found guilty again," Bachrach said. 
 
 Just last month Knox learned that the Italian Supreme Court ordered a new trial, meaning her marathon legal battle would continue for her and Sollecito. 
 
 Knox said the court's decision was "painful" and "completely unfounded and unfair." 
 
 The new trial is expected to start sometime next year, according to Knox's lawyer. 
 
 Since her release from prison, Knox has resumed her life in Seattle, taking classes and spending time with her family and boyfriend, James Terrano. 
 
 Knox's first interview since she was freed will air during a primetime special on Tuesday, April 30 at 10 p.m., ET on the ABC Television Network.
– Amanda Knox's new book describes a traumatic, harrowing ordeal as she was imprisoned for four years for a murder she says she didn't commit—but in some cases, the memoir is at odds with earlier accounts she gave, such as letters she wrote and even her own diary, the BBC reports: Though her memoir reportedly describes sexual harassment at the hands of prison guards, she described the staff as "really nice" in the diary, which was published in Italy. "They check in to make sure I'm OK very often and are very gentle with me." As for the prison itself, she called it "pretty swell." In her memoir, she writes that she was "weak and terrified" and coerced into falsely accusing Patrick Lumumba of Meredith Kercher's murder; she says a prison guard told her to write down the accusation quickly. But in a letter she sent lawyers after making the written declaration to police, she says nothing about being rushed, writing simply, "I tried writing what I could remember for the police, because I've always been better at thinking when I was writing. They gave me time to do this." Her memoir also describes a medical examination at the police station, during which she was stripped naked and told to spread her legs. She calls it "the most dehumanizing, degrading experience I had ever been through." But in the aforementioned letter to lawyers, she made it sound routine and simply said she was "checked out by medics." Click for the full report.
