Query: One long excruciating non-stop depiction of horror

This is a non-stop narrative, just one chapter, no breaks. Semprun never learned the name of his companion on the box-car ride, so he simply calls him "the guy from Semur." Sadly, the guy never got out of the box car. Semprun survived the box car and spent more than two years in Buchenwald, which he hardly describes.But Semprun achieves literary stardom in his depiction of the S.S. murder of 15 Jewish children who somehow survived the voyage of horror -- without food or drink.There is just one flaw. The gate of Buchenwald did not say "Arbeit macht frei!" It quoted Shakespeare: "To Each His Own." ("Jedem das Seine.")
