With a screech that raised my hair, Grue whipped out his murderous knife and hurled himself backward at Kemper, but the latter shrank aside behind the partly erected cage, and Grue whirled around, snarling, hacking, and even biting at the wood frame and steel bars.
And then occurred a thing so horrid that it sickened me to the pit of my stomach; for the man's sagging straw hat had fallen off, and there, in the back of his head, through the coarse, black, ratty hair, I saw a glassy eye glaring at me.
"Kemper!" I shouted. "He's got a third eye! He's one of them! Knock him flat with your riflestock!" And I seized a shot-gun from the top of the baggage bundle on the ground beside me, and leaped at Grue, aiming a terrific blow at him.
"'Kemper!' I shouted.... 'He is one of them! Knock him flat with your riflestock!'"
But the glassy eye in the back of his head was watching me between the clotted strands of hair, and he dodged both Kemper and me, swinging his heavy knife in circles and glaring at us both out of the front and back of his head.
Kemper seized him by his arm, but Grue's shirt came off, and I saw his entire body was as furry as an ape's. And all the while he was snapping at us and leaping hither and thither to avoid our blows; and from the corners of his puffed cheeks he whined and whimpered and mewed through the saliva foam.
