Scientific sleuthing and slip-ups in the investigations of fifteen famous cases Ranging from the Turin Shroud and the suspicious death of Napoleon Bonaparte to the murder cases of Dr. Sam "The Fugitive" Sheppard and O. J. Simpson, A Question of Evidence takes readers inside some of the most vexing forensic controversies of all time. In each case, Colin Evans lays out the conflicting medical and scientific evidence and shows how it was used or mishandled in reaching a verdict. Among the other cases: the assassination of JFK, the strange history of Alfred Packer (the only convicted American cannibal), the death of Vatican banker Roberto Calvi, and the trials of Lindy Chamberlain (the "dingo baby" case) and Dr. Jeffrey MacDonald (the case recounted in Fatal Vision). Though the science of forensics has helped solve a huge number of crimes, it"s clear from A Question of Evidence that many cases are more open than shut. Colin Evans (Pembroke, UK) is the author of the popular Casebook of Forensic Detection (Wiley: 0-471-28369-X) as well as Great Feuds in History (Wiley: 0-471-38038-5).
