 Nocturnal insects? Ordinarily, I'd say that was a distinct possibility if it weren't for the fact that our surveys show no evidence whatsoever of any such insects on Glade. Your survey could have missed them, couldn't it? Not if they existed in any great quantity. Besides, if insects were the answer, there should be some kind of evidence of them right here in the area where Ethel was lying. Certainly one or two of them would be crushed when she rolled over in her sleep.
