27. THE WOLF IN SHEEP'S CLOTHING
A Wolf resolved to disguise himself in order that he might prey upon a flock of sheep without fear of detection. So he clothed himself in a sheepskin, and slipped among the sheep when they were out at pasture. He completely deceived the shepherd, and when the flock was penned for the night he was shut in with the rest. But that very night as it happened, the shepherd, requiring a supply of mutton for the table, laid hands on the Wolf in mistake for a Sheep, and killed him with his knife on the spot.
