An instantly absorbing piece, with meticulous reporting from Tom Lamont, who has clearly put the time in with Nazi hunter Thomas Will to understand his complicated profession. It’s a disturbing and thought-provoking look at the last Nazis who will ever face trial, with particular focus on the fascinating case of Irmgard Furchner, put on trial at 96 for her role as a civilian secretary at Stutthof camp.

He is one of the last in a long line of Nazi hunters, the chief of a German bureau created decades ago to investigate historic atrocities and to track down aiders and abettors of the Holocaust—those few that remain. All these years after the collapse of the Third Reich, many of the suspects that Will tries to bring to justice die on him.
