Marsh and Durbin had been fortunate in getting away in the dark passages of the old castle, and Buckhart followed Aaron in his pursuit of MacLane. Brad witnessed the peril of the little man, and fired to save him from being dashed from the wall. Following the shot, both men fell.

Buckhart retraced his steps and heard Dick calling to him. Guided by Merriwell’s voice, he came upon Dick, who was supporting Budthorne with one hand and holding a torch with the other.

“Perhaps we had better get out of here before those chaps recover and realize there are so few of us,” said Dick. “I think Budthorne is all right, and we’ve had great luck.”

“Luck!” cried the fighting Texan. “No luck about it, pard! I opine it was a case of pure sand, and we won the game on our merits.”

He then told what had happened on the old wall.

They lost no time in getting outside and aiding Budthorne to the spot where the terrified professor waited with the boat.

“But we’re not going away without finding out what has happened to Aaron,” said Dick. “Come on, Brad.”

They went in search of the little man and found him under the wall, his leg broken. Near at hand lay another man, who had something worse than a broken leg, for a bullet had pierced his shoulder and his neck had been broken when he struck the ground.

Innocent persons in that part of the country would never more be terrorized by Rob MacLane.

After a long consultation with Budthorne and his sister, it was decided, on Dick’s advice, that Dunbar and Nadia should quietly leave Scotland for Italy. Dick and Brad promised to meet them, if possible, after they had visited several points of interest in England, upon which the professor insisted.
