PositiveThe New York Times Book ReviewWhat specifically distinguishes Marwell’s account from previous studies concerns his personal involvement in the Justice Department’s Office of Special Investigations (O.S.I.) and the search for and identification of Mengele. Much of the volume is taken up with Mengele’s escape to, and life in, various South American countries and the bungled attempts to locate and capture him ... There is also highly detailed reportage regarding the seemingly endless investigations and multiple conflicts surrounding the interpretation of the medical and forensic evidence that in 1992 definitively established that Mengele had died in Brazil in 1979.
