Just finished reading 'The Emperor of Lies' by Sandberg. It is based on the chronicles kept by the administration of the Jewish ghetto in Lodz in Poland, which was the second largest after Warsaw.
It was ruled by Chaim Rumkowski who co-operated with the Nazis through the production of Wehrmacht uniforms and housing materials in turn for what he claimed was slowing down the deportations to the death camps. Indeed it appears to have been fairly late before he accepted that they were going to death camps. Others claim that he knew all along.
He was an unpleasant character who sexually abused children in the orphanages and who profited from the ghetto factories. He came to an unfortunate end in that he thought he had negotiated a deal for himself and family when the ghetto was closed down in August 1944 but was in fact sent to Auschwitz where he was killed the moment he arrived or perhaps even by other deportees on the train.
Brilliant book and higlights the complexities of the war where locals including ghetto Jews were collaborating with the Nazis. Indeed the Jewish ghetto police in Lodz were a particualry nasty gang.
