"I charge you with being notorious burglars, with lying here ready to commit another offence. My witnesses, who overheard you discussing your plans, are Mister Clive Darrell and Mister Hugh Seymour."

Very pompously did the sergeant give the information. The man called Joe looked as if he would explode, so great was his indignation. But though the mention of our two young friends' names may have meant nothing to him, they seemed to attract the attention of another of the three who stood in the background till that moment almost unobserved. He started forward, looked closely at Clive and Hugh, and then, to the amazement of his comrades and all present, broke into a fit of uncontrollable laughter. He almost grovelled in his ecstasy. The Rector was really alarmed for the man's reason, while Bill Watson, the smith, stepped farther away and raised his iron bar in readiness for self-protection. It was Joe and the sergeant who first noticed the curious change which had come over Clive and his young friend. They were backing away. They looked horribly frightened. Clive had gone a fiery red, while Hugh was almost purple. They looked, in fact, as if they had seen the ghost said to haunt this ancient tower, and as if the sight had scared them out of their wits.

"I—I think we'd better be going," Clive managed to blurt out at last.

"Er—yes," agreed Hugh huskily.

"One moment, young gents," said the sergeant. "Why, if that chap ain't still laughin'. See here, my man, you just cut it short, or——"

He was interrupted by another gust. The burglar immediately in front of the one so vastly amused joined him in his merriment. Then Joe saw the fun, wherever it existed, and presently there were all three shaking with mirth, while their captors looked on sternly. And then the one who had set the fashion stepped to the front, torn and dishevelled after his encounter. Clive and Hugh backed away, and would have bolted, but at a glance from him stood rooted to the spot.

"Sergeant," said the man, "I'm Mr. Canning, a master at Ranleigh School. Ask those boys if they recognise me."

No need to ask. The faces of our two young friends supplied the answer. It was actually and decidedly Mr. Canning, the "Peach," as many called him, because of his blooming cheeks, the master so fond of giving "impots." Clive groaned aloud as he looked at him. Hugh wished the remaining roof of the chapel might fall in and bury him yards deep.

"Oh!" exclaimed the sergeant, looking glum of a sudden.

"And these are my friends. Mr. Oxon here, whom we call Joe, is the owner of Merton Tower. To proceed, there is a legend of buried treasure. He has lately come upon a clue hidden away in an ancient family manuscript. What more natural than that he should invite his friends to help him search for the missing valuables? What more natural than that the strictest secrecy should be employed? That these boys have discovered us is unfortunate. The fact that we have been taken for burglars is readily understood. It is a most excusable and humorous mistake. Allow me to assure you that we are the most harmless of individuals. As to the boy who fell into the chapel, he is merely stunned. We have been wondering how he managed to get into the tower. I suppose I should have recognised him. I didn't. As to the shots, we were merely amusing ourselves with a six-shooter. There. You have a full explanation."
