“Never mind who told me.  What I want to know is, did you sleep after you let him in or before?”

“Why, I—­I—­really—­”

“Tell me the truth, Smith.”

“I guess I took a nap afterwards, sir.  But it was only for a minute, sir,” pleaded the cadet.

“I see.  Did you see the outsider leave camp after you had let him in?”

“Why, sir—­I—­I—­”

“I want the strict truth, remember, Smith.  If you don’t tell the truth you may get yourself in great trouble.”

“Oh, Captain Putnam, I—­I didn’t mean to do anything wrong!”

“Did you see the outsider leave again or not?”

“Yes, sir, I saw him leave?”

“How soon after he had come in?”

“About fifteen or twenty minutes,—­certainly, not much longer than that.”

“Now, who was the outsider?”

“Why, I—­er—­I—­”

“Answer me, Smith!” And now Captain Putnam’s voice was as keen as the blade of a knife.  He stood before the frightened cadet, looking him squarely in the eyes.

“It was Lew Flapp.  But, oh, please, don’t let him know I told you!  He’ll kill me if he finds it out!” Link Smith was about ready to cry.

“Lew Flapp.”  The captain drew a long breath.  “How did you come to let him in?  You knew he had been dismissed from the school.”

“He begged me to let him in, saying he merely wanted to speak to two of his old friends.  I asked him why he didn’t wait until morning, but he said he wanted them to do something for him before they left the school—­that he must see them then and there.”

“Did he mention his friends’ names?”

“No, sir.”

“What did he say when he went away?”

“Nothing much, sir, excepting that he had seen them and it was all right.”

“Where did he go to?”

“I don’t know.  It was dark and I soon lost sight of him.”

“He came alone?”

“Yes, sir.  But, please, Captain Putnam, don’t tell him I told you, or he’ll kill me.”

“Don’t be alarmed, Smith.  I’ll protect you.  If you see Flapp again tell me at once.”

“I will, sir.”

This ended the examination of Link Smith, and as soon as it was over the remainder of the cadets who had been on guard duty the night before were likewise told they might go.

CHAPTER VII

FUN ON THE CAMPUS

“It was Lew Flapp, just as I supposed,” said Dick, when he heard the news from Captain Putnam.  “What a rascal he is getting to be!  Almost as bad as Dan Baxter.”

“Oh, he would have to be a good deal worse than he is to be as bad as Dan,” returned Sam.  “But I admit, he is bad enough.”

“I’d give some money to lay my hands on him,” put in Tom.  “Oh, but wouldn’t I punch his head good and hand him over to the police afterwards!”

Word was sent to Josiah Cotton and other officers of the law to look for Flapp, but for the time being nothing was seen or heard of that individual.
