"Rainer walks over to a metal door with a small hole in it. This is the back door to the old crematorium. This is where his grandfather looked through the peephole and watched the prisoners being gassed to prove to his staff that he could cope with the mass murders taking place under his watch." (p.285)
“I had to look through the peephole of the gas chambers and watch the process of death itself, because the doctors wanted me to see it. I had to do all this because I was the one to whom everyone looked, because I had to show them all that I did not merely issue the orders and make the regulations but was also prepared myself to be present at whatever task I had assigned to my subordinates."
"The southeast access to the second air lock of the air raid shelter for the SS hospital ... This entrance led directly to the former gas chamber of Krematorium I. Though it had nothing to do with the gas chamber it was preserved during the restoration, whereas it should have been filled in to respect historical facts."
