Portrait of a Killer: Case Closed

by Patricia Cornwell

Using the first-hand expertise she has gained through writing the best-selling Dr Kay Scarpetta novels, Patricia Cornwell has used the demanding methods of modern forensic investigation to re-examine the contemporaneous evidence in the Jack the Ripper murders. These include state-of-the-art DNA testing on various materials, computer enhancement of watermarks, and expert examinations of hand-writing, paper, inks, and other relics.
