"Yes, sir; I saw Herbert lock it in the case, and he's had the key ever since."

"Did you leave the case about anywhere?"

"No, sir; I brought it straight home, and put it on your table."

"Do you know anything about it, Herbert?"

"No, sir," answered the cricket captain, whose face was as long as a fiddle. "I locked the cup in the case, and gave it to Buckle; and I only just remembered that the key was still in my pocket."

"Well, this is most extraordinary!" said Mr. Conway blankly. "It sounds like one of those tricks shown by Maskelyne and Cook. You must be mistaken, Herbert. This must be inquired into at once."

A few minutes later an excited crowd surged out of the dining-hall. Every one was talking at once, the result being a perfect babel of sound. The Cock-house Cup was missing; by some extraordinary means it had been spirited away from its rightful owners. In the whole history of Hadbury College such a thing had never been heard of before.

Each boy had a different opinion to offer: one thought that Herbert or Buckle must have left it behind on the ground; another believed a burglary had been committed; while a third made the somewhat rash assertion that the Morganites might have collared it out of spite, though how this could have been done he was not prepared to explain.

A few of the seniors did not doubt that the cup would be found somewhere in the house-master's study, but a careful search afforded no further clue towards a solution of the mystery; in fact, the theory of a robbery seemed untenable, since not a single article in the room had been disturbed or removed from its accustomed place.

The startling fact at length forced itself upon the minds of all concerned. The Cock-house Cup, Hadbury's most cherished and honoured trophy, had, in some mysterious manner, disappeared; added to which was the unpleasant reflection that Conway's would be held responsible for its loss.
