5. In the middle of the night a great noise in the room woke the master, and he got up to see what was the matter. There, on the floor, was a man flat on his back, while Nero stood over him growling in a way that said, “Lie still if you wish to keep a whole skin.”

6. The man was tied and taken to prison, and he proved to be a robber who had come to steal the master’s purse, and perhaps to kill him.

7. What made the dog leave his own bed and go up to the room of his master nobody knew; but he seemed to think that his master was in danger, and so he went up to help him.

8. You may be sure that Nero was well treated after this, and he could sleep where he pleased; but he went back to his kennel, as though he knew it was his place to keep watch out-of-doors.

9. He lived to be a very old dog, and he had the best of care until he died.
