Robert A. Heinlein on Cannibalism in literature

“"I despised him long before I found out about his having young girls butchered and served for his dinner.... Ponse always ate girls. About one a day for his family table, I gathered. Girls about the age and plumpness of [14-year-old] Kitten." "But— But— Hugh, I ate the same thing he did, lots of times. I must have— I must have—" "Sure you did. So did I. But not after I knew. Nor did you." "Honey... you better stop the car. I'm going to be sick."”

“Hugh tried to keep his eyes [off] the contents of the meat storage room. Most of the meat was beef and fowl. But one long row of hooks down the center held what he knew he would find – human carcasses, gutted and cleaned and frozen, hanging head down, save that the heads were missing. Young sluts and bucks, he could see, but whether the bucks were tempered or not was no longer evident.... Memtok paused on the way out and patted the loin of a stripling buck carcass. "That's what I would call a nice piece of meat. Eh, Hugh?"”
