“I was a fool.”

“No, for I learned to care a great deal for Nadia, and in time I decided that for her sake you must be saved. In order to save you I decided to marry her.”

In spite of his weakness, Budthorne struggled to his feet as if to attack Bunol, but he was forced to lean against the wall for support.

“Don’t excite yourself too much,” urged the Spaniard, with mock solicitude. “You are not strong.”

“No, no!” groaned Budthorne. “My legs will scarcely bear my weight. I believe you somehow contrived to drug me, you wretch!”

Bunol smiled, thinking of the drug he had given Aaron.

“You do me great injustice,” he protested. “Let me continue. I resolved to marry your sister, for I felt she stood in great need of a faithful guardian who would care for her tenderly and prevent you from squandering her share of the fortune. Little by little I gained influence and control over you, and I should have succeeded in full but for the interference of that fellow Merriwell. He upset all my plans. Had those plans worked as they should, the moment I became sure of Nadia I should have cast aside both Durbin and Marsh. Rid of them, I could cause you to cease your recklessness and prevent you from squandering what remained of your fortune. You see, Budthorne, my intentions toward you were of the most friendly sort.”

“Bah!” cried the captive.

“After the exposure in London,” Bunol went on, “I succeeded in following you here, leaving Marsh and Durbin behind. With the aid of a faithful fellow, good fortune led me to meet, I planned to get hold of you, just as I have, in order to talk reason to you. I could have done very well without Marsh and Durbin, but it chanced that they followed Merriwell and his companions to Ben Cleuch, and they were passing on the highway when I hailed them. I thought it best to use them once more this night, and then to get rid of them forever. They think I am now trying to squeeze from you more money that is to be divided equally between us. Thus they deceive themselves. If you have in your head the reason you should, it is little they will get.”

“What are you trying to propose?” demanded Budthorne.
