"Nothing special, why?"
"Well, I'll not tell you the particulars, and then, if anything happens you can truthfully say you never knew a thing about it. But if you want to see something, put on an old pair of slippers, so you can walk through the corridors softly, and follow us."
"Some fun?" asked Jack.
"Well, we wouldn't go to all this trouble if it was work or study," replied Sam with a grin. "But say nothing, only saw wood and come on."
Jack, nothing loath, did as he was told. He got an old pair of felt slippers, and noticed that the others were also wearing similar foot-gear.
"First to Professor Socrat's room," whispered Sam when the boys, including Will Slade, Fred Kaler and Bony Balmore were out in the corridor.
"He's not going to fight a duel with Professor Garlach, is he?" asked
Jack, recalling an occasion when the two teachers nearly did.
"Not this time," replied Sam, "but there may be a fight in it."
With Sam in the lead the boys went to the room of the French professor.
"Now stay back in the shadows," advised the leader. "You can see and listen, but keep quiet."
