The room was a small chamber set apart for music practice, the only furniture it contained being a piano, a chair, some fiddle-cases, and music-stands, while on the mantelpiece, in the place of a clock, was a metronome that had something wrong with the works. Jack, however, had no eye for these details; his attention was centred in a group of boys who were struggling under the single gas-jet, which was flaring away in a manner which showed it had evidently been turned up in a hurry.

"Here, leave that chap alone!" he exclaimed, plunging into the centre of the scrimmage. "Let him alone, I say!"

"Hallo! it's Fenleigh J.," cried Garston. "You've just come in time to help us to teach this cousin of yours a lesson on the subject of not overworking himself."

"Leave him alone!" repeated Jack angrily, giving Rosher a push which sent him staggering back into the fireplace, where he knocked over the metronome, which fell with a crash on the fender.

"Don't be a fool, Fenleigh," cried Teal. "We're going to teach this chap a lesson. If you don't want to help, you can clear out."

"I shall do nothing of the sort," returned the other. "You let him alone."

Both parties were too much in earnest to waste their breath in talking, and the next moment Garston and Rosher sprang on the intruder and endeavoured to force him out of the room. Valentine, being unable to free himself from the muscular grasp of Teal, could render no assistance; but his cousin, whose blood was fairly up, struggled furiously with his two assailants. Round the room they went, like a circular storm, wrecking everything they came in contact with; music-stands went over with an appalling clatter, while the back of the solitary chair gave way with a crash as the three combatants fell against it. Suddenly a sharp voice sounded down the passage,—

"Now then, there! What's all that noise about?"

Teal released his hold of Valentine, and springing to the gas-jet turned out the light.

"Cave!" he whispered: "it's old Thorpe!"
