"And who assisted you?"

To this inquiry Thurston would give no reply, but maintained a dogged silence. Gull and Hawley, however, anxious at all costs to save their own skins, practically answered the question by saying, "We didn't," and casting significant glances at Noaks and Fletcher.

What followed it is hardly necessary to describe in detail. The five culprits were subjected to a merciless cross-examination, during which a confession, not only of their various transgressions, but also of the motives which had prompted them to adopt such a line of conduct, was dragged from their unwilling lips. The cloak was torn off, and the cowardice and meanness of their actions appeared plainly revealed, and were forced home even to their own hearts.

"Thurston and Fletcher," said the doctor, when at length, long after the bell had rung for "interval," the inquiry concluded, "go to your studies, and remain there till you hear from me—Noaks, go in like manner to the housekeeper's room.—Gull and Hawley, as you seem to have taken no active part in this last misdemeanour, you may go. As regards your previous misconduct, I shall speak to you on that subject when I have decided what is to be done with your companions."

For the Triple Alliance the remainder of the day passed in a whirl of conflicting emotions. In a very short time the whole school knew exactly what had taken place in the doctor's study, and every boy was incensed at the underhanded meanness of this attempted attack on Oaks and Allingford. It was a good thing for Thurston and Fletcher that they had their studies, and Noaks the housekeeper's room, in which to find shelter, or they would have been compelled to run the gauntlet. Hawley and Gull, though not found guilty on this particular count, were hustled and abused for their former misdeeds, which it was perfectly evident would be remembered against them during the remainder of their life at Ronleigh.

As for Diggory and his two chums, never were three small boys made so much of before. "What was the cipher?"—"How did they find it out?"— these and a hundred other questions were continually being dinned in their ears, coupled with slaps on the back, ejaculations of "Well done!"—"You're a precious sharp lot!" and many other expressions of approval.

At the close of this eventful day two things alone remained vividly impressed upon their minds.

The first was an interview with Allingford and Oaks in the former's study.

"Well," said the captain, "you kids have done us a good turn. We were in a precious awkward box, and I don't know how we should have got out of it if it hadn't been for you."

"Yes," added Oaks: "I was never more surprised at anything in my life than when Trevanock said he knew who'd done the business. It made old Denson open his eyes."
