More than 800,000 people entered Treblinka, and fewer than seventy came out. Hershl Sperling was one of them. He escaped. Why then, fifty years later, did he jump to his death from a bridge in Scotland? The answer lies in a long-forgotten, published account of the Treblinka death camp, written by Hershl Sperling himself in the months after liberation and discovered in his briefcase after his suicide. It is reproduced here for the first time.
