"So you've been studying the Yig-legend, eh?" he reflected sententiously. "I know that many of our Oklahoma ethnologists have tried to connect it with Quetzalcoatl, but I don't think any of them have traced the intermediate steps so well. You've done remarkable work for a man as young as you seem to be, and you certainly deserve all the data we can give. "I don't suppose old Major Moore or any of the others told you what it is I have here. They don't like to talk about it, and neither do I. It is very tragic and very horrible, but that is all. I refuse to consider it anything super-natural. There's a story about it that I'll tell you after you see it--a devilish sad story, but one that I won't call magic. It merely shows the potency that belief has over some people. I'll admit there are times when I feel a shiver that's more than physical, but in daylight I set all that down to nerves.

"Did you see that single ground-glass basement window over in the east wing when you came up the drive? That's where it is. I'll take you there myself now. You needn't make any comment. Just look through the movable panel in the door and thank God the light isn't any stronger. Then I'll tell you the story--or as much as I've been able to piece together." We walked downstairs very quietly, and did not talk as we threaded the corridors of the seemingly deserted basement. Dr. McNeill unlocked a gray-painted steel door, but it was only a bulkhead leading to a further stretch of hallway. At length he paused before a door marked B 116, opened a small observation panel which he could use only by standing on tiptoe, and pounded several times upon the painted metal, as if to arouse the occupant, whatever it might be.
