"Peter knew that a tunnel ran underneath the walls of the town and that the other end of it opened by a trap-door into a stable in Lucerne," went on the old man without noticing Leneli's interruption, "and at once he saw that some traitor must have told the Austrians of this secret passage. He crept closer and closer to the group of men, until he was near enough to hear what they said. You may be sure his blood ran cold in his veins when he heard the voice of a man he knew, telling the Austrians just how best they could capture the town! He knew that terrible things would happen in Lucerne that night if the enemy ever reached the other end of the tunnel, and at once made up his mind that he must alarm the town. He dropped on his hands and knees and was beginning to crawl back toward the entrance, when he heard some one coming into the tunnel! He sprang to his feet and tried to run past, but the passage was narrow, and he was caught at once and dragged into the light."
"Oh! Oh!" gasped the Twins, breathless with excitement. "It sounds just like a bad dream."
"It was no dream," said the old herdsman, "for when the traitor, whose name was Jean de Malters, saw Peter, he was terribly angry.
'How did you come here,' he roared, in a voice that made the earth shake.
"'I was asleep on the bank and you woke me up, so I followed to see what was going on,' said Peter.
"'I don't believe you. Some one sent you to spy upon us,' said Jean de Matters, and he shook Peter. 'Who sent you?'
"'No one,' said Peter. 'I have told you the truth.'
"'You lie,' said his captor. "I give you just two minutes to tell who sent you, and if you do not tell us then, you shall die!'
"Poor Peter thought of his home and his mother and father, and there never was a more homesick boy in the world than he was at that moment, but though he was terribly frightened, he did not say a single word.
"'He shall die, then,' said Jean de Falters, when the two minutes were up, and Peter had not spoken.
"One of the Austrians interfered. 'No,' he said. 'It would be bad luck to begin the night's work by shedding the blood of a child.
Make him swear he will not tell what he has seen to any living soul, and let him go.'
"In spite of Jean de Matters, who was bound that he should be killed, that was what they did, and the moment he was free you may be sure Peter ran like the wind for home.
"Now you see," said the old herdsman, and he shook his finger at Seppi and Leneli, "I this was a dreadful position for Peter. He had solemnly promised not to tell a living soul what he had seen and heard, but if he didn't tell, his parents and friends would be murdered before morning.
"That evening his father and a number of other men were gathered together in the town hall of Lucerne to talk over community affairs, when Peter suddenly burst into the room, his eyes as big as saucers.
"The men gathered about him, thinking he must have some tremendous piece of news, but Peter spoke never a word to them.
Instead, he marched up to the great porcelain stove that stood in the room.
"'O Stove,' said Peter, 'I have just heard terrible things which I have promised not to tell to a living soul, but you, O Stove, have no soul, so to you I will say that the Austrians are now in the tunnel underneath the walls and that at midnight they will break in and sack the town.'
"At first the men thought Peter had gone crazy, but when he had finished telling the stove all he had seen and heard, they flew to alarm the town and get their weapons.
"At midnight, when the Austrians came up through the hole in the stable floor, they were received by a little army of men of Lucerne, and in the battle that followed they were completely whipped and driven from the town forever. And it was Peter who saved the city.
"You see that was Peter's chance to show what he was made of, and he didn't miss his chance. He did the right thing, even though he was afraid. It's a great thing not to miss one's chance."
The old herdsman looked up at the moon as if he hadn't meant any one in particular when he said that about missing one's chance, and the children didn't say a word for a minute.
Then Seppi said, "If Peter could save a whole town, I guess we can get down that pass with a few goats."
"Why, of course," said the herdsman. "It's your chance, you see, and when you get home very likely you'll find you are both heroes. You see if there were never any danger, there never could be any heroes at all! Now climb up into the hay, both of you, and I'll wake you for an early start in the morning."
