Known for his sadistic medical experiments on Jewish prisoners at Mauthausen concentration camp, Dr Aribert Heim disappeared ahead of his imminent arrest for his crimes in 1962. In the years and decades that followed, there were reported sightings of him all over the world, in locations as far apart as Uruguay, Egypt, Chile and Spain. Here is the dramatic story of how a clandestine organization, comprised of Vietnam War veterans and former secret agents, plotted to assassinate him. Baz tells his extraordinary story of life from inside the secretive cell, and a tireless manhunt that took him from the US to Israel, Germany and Canada in order to find the evil fugitive known as `Dr Death’. This is an astonishing, controversial and fascinating account of a story that remains little-known to the public despite Heim’s status as one of the most notorious Nazi war criminals. Danny Baz is a retired Israeli Defence Force colonel who joined the covert `search-and-destroy’ death squad, `The Owl’, in the 1980s out of a desire to avenge the killings of family members in the Holocaust.
