Goat held up a stern hand, enforcing silence. "I can't certainly settle this disagreement, but I'd be inclined to accept what Brute says," said Goat thoughtfully. "You're smart enough to lie, Adam. Brute isn't. The only thing I can do is to run the experiment over. You shall go out again tomorrow, and this time I'll go with you." "You'll see, father," said Adam confidently. "Adam will not fall." "Perhaps not. But I must be sure. As much as I prefer your more human characteristics, Adam, it's entirely possible that Brute has some survival qualities that you lack." "Is true, father," said Brute eagerly. "Some things kill Adam, they not kill Brute." "You lie!" cried Adam again, turning on him. "Why do you lie, Brute?" "No lie," insisted Brute. "You know, is true." "Lie! Lie!" shouted Adam. "Adam is bigger and stronger! What do you say can kill Adam that does not kill Brute?" "This," replied Brute calmly. With an unhurried lunge, he picked up a heavy knife from Goat's desk. In a single easy movement, he turned and slashed Adam's throat neatly. Choking and gurgling, Adam sank to his knees, bright blood spouting from his neck, while Goat stood frozen in horror. Adam fell prone, he kicked and threshed convulsively like a beheaded chicken, then twitched and lay still in a spreading pool of blood. Brute calmly wiped the knife on his naked thigh and laid it back on the desk. "Adam dead," he said without emotion. "Brute not lie." Dismayed fury erupted through Goat's veins and a red haze swept over his eyes. "You idiot!" he squawked. "So that won't kill you?"[Pg 15] [Pg 15] Goaded beyond endurance, Goat seized the knife and swung it as hard as he could against Brute's neck. It thunked like an ax biting into a tree trunk, biting halfway through the flesh. Brute recoiled at the impact, tearing the handle from Goat's feeble hands and leaving the knife blade stuck in his throat.
