He was silenced by the same unfailing method which had just been brought to bear upon his companion.

A short conversation took place between the masked figure who had acted as spokesman and the person within. At the end of it the former turned to his companions.

"Blindfold the novices. The Keeper of the Portal has commanded it."

Keeper of the Portal? That, then, was the meaning of the initials "K. O. P." thought Plunger.

It was getting more and more mysterious, but he did not like the idea of being blindfolded. What were they going to do with him—with Moncrief? At first he felt inclined to resist, but a sharp twist of the wrist soon convinced him that resistance was useless. Harry had come to the same conclusion, so they submitted with the best grace they could to bandages being placed round their eyes. Then they heard the door open and the voice of the "Keeper of the Portal" commanding them to enter.

They entered. As they did so, Plunger thought he heard some one sniggering, and again a wild idea crossed his mind that he would strike out and make a desperate effort to escape from his captors; but the instant he moved he was brought to a standstill by the energetic measures which were now becoming painfully familiar to him.

The sniggering, if sniggering it was, soon ceased, and then a strange silence reigned in the barn. The silence was a great deal worse to Plunger than any amount of ridicule. Who were in the barn? What was happening?

He strained his ears to the utmost. He could hear the sound of mysterious footsteps walking stealthily to and fro, but no one spoke. He stood there and shivered, though the perspiration was oozing from his forehead. Was some desperate plot on foot against them? The footsteps ceased. All was again so still that he began to think the barn had been deserted and that he had been left in it blindfolded, to make his way from it the best he could. He was about to call out to Harry when a voice he had not yet heard called out sharply:

"Gargoyle with the eyebrows, what is thy name?"

Gargoyle with the eyebrows!
