In 2001, #1 New York Times bestselling crime novelist Patricia Cornwell was pulled into a real-life investigation of her own--the long-unsolved and deeply unsettling "Jack the Ripper" murders that mesmerized London in the late 1800s. Applying modern science and forensic techniques to a century-old crime, Cornwell's research led to the publication of Portrait of a Killer, in which she identified the renowned British painter Walter Sickert as the Ripper. The book became a #1 bestseller but also embroiled Cornwell in controversy as Ripperologists dismissed her claims and her credibility. But for Cornwell, the book was only the beginning. For more than a decade, Cornwell has devoted countless hours and invested millions in her pursuit of new evidence against Sickert. Now, twelve years later, Cornwell revisits the most notorious unsolved crime in history--determined to solve the mystery once and for all.In this exclusive Kindle Single, Cornwell restates her case against Sickert, unveils new evidence, clarifies his motivations, and makes him human--and, along the way, explains how such a prominent cultural figure could be a notorious killer. She also directly faces down her critics with withering skill and, in doing so, is likely to re-ignite the debate over history's most heinous unsolved crime.Chasing the Ripper offers a surprisingly personal and revealing look into what it has been like for Cornwell to pursue the most sensational murder case in criminal history--even as she continues to thrill her fans with a steady diet of new Scarpetta novels, including Flesh and Blood, her latest New York Times bestseller.
