The Wolf in Sheep's Clothing

A Wolf found great difficulty in getting at the sheep owing to the vigilance of the shepherd and his dogs. But one day it found the skin of a sheep that had been flayed and thrown aside, so it put it on over its own pelt and strolled down among the sheep. The Lamb that belonged to the sheep, whose skin the Wolf was wearing, began to follow the Wolf in the Sheep's clothing; so, leading the Lamb a little apart, he soon made a meal of her, and for some time he succeeded in deceiving the sheep, and enjoying hearty meals.

One evening, as the sun was setting and the flock was settling into the fold, the shepherd came to count his sheep before closing the gate. The Wolf in Sheep's clothing stood among the flock, trying to appear as innocent as the rest. But the shepherd, whose eyes were sharp and whose experience was great, noticed something strange about one of his sheep -- its stance was too alert, its eyes too cunning, and its manner too bold.

The shepherd moved closer, examining the supposed sheep carefully. What he saw made his heart pound -- the wool was merely a cloak, and beneath it lay the gray fur of a wolf. Without a moment's hesitation, the shepherd drew his knife and ended the deceiver's life, saving the flock from harm.

Evil doers who camouflage themselves as good will eventually be exposed and punished for their deeds.
