Steve was now progressing finely with the work on the Kane Aircraft and believed he would be able to overcome all the imperfections that had disclosed themselves during the first trial. Mr. Cumberford came to the hangar nearly every day, now, and Steve and Orissa began to wonder how he found time to attend to other business—provided he had any. On the day of Tyler’s visit he had announced it was his last trip to see the Kanes, as he had been summoned to Chicago to attend a directors’ meeting and from there would go on to New York. But having discovered that Burthon was intent upon some secret intrigue, which could bode no good to his protégés—the Kanes—he promptly changed his mind and informed Steve on a subsequent visit that he had arranged affairs at home and was now free to spend the entire winter in Southern California.
“My daughter likes it here,” he added, “and kicks up fewer rows than she does at home; so that’s a strong point in favor of this location. 106Aviation interests me. I’ve joined the Aëro Club out here and subscribed for the big meet to be held in January, at Dominguez Field. That’s when we are to show the world the Kane invention, my lad, and I think it will be an eye opener to most of the crowd present.”
“How does your mine, the Queen of Hearts, get along?” asked Orissa.
“It continues to pay big—even better than I had hoped. Burthon must be pretty sore over that deal by this time. Speaking of my sainted brother-in-law, I’ve just made a discovery. He owns the mortgage on your place.”
“Why, we got the money from the Security Bank!” exclaimed Orissa.
“I know. I went there. Thought I’d take up the mortgage myself, but found Burthon had bought it. Now, the question is, why?”
Neither brother nor sister could imagine; but Cumberford knew.
“He hopes you won’t be able to meet it, and then he’ll foreclose and turn you out,” he said. “But you’re not the principal game he’s after; he’s shooting me over your heads. Burthon is miffed because I let you have the money, but believes I haven’t any financial or personal interest in you beyond that. If he can prevent your aircraft from flying he’ll make me lose my money 107and also ruin you two youngsters. That’s doubtless his game. That’s why he sent his man here to spy upon you.”
“But that is absurd! Burthon can’t prevent our success,” declared Steve. “Even if some minor parts go wrong, the aircraft will fly as strongly and as well as anything now in existence.”
“Don’t be too sure,” cautioned Mr. Cumberford. “You and your machine may be all right, but that’s no reason why Burthon can’t push failure at you, or even prevent you from flying. We must watch him.”
“I do not believe the man hates us,” observed Orissa, thoughtfully. “Mr. Burthon is a little queer and—and unscrupulous, at times; but I don’t consider him a bad man, by any means.”
“I know him better than you do, and he hates me desperately,” replied Cumberford.
“He says that—that you abused his sister,” doubtfully remarked the girl.
“Well, I did,” said Cumberford, calmly. “I pounded her two or three times. Once I choked her until it’s a wonder she ever revived.”
“Oh, how dreadful!” exclaimed Orissa, shrinking back.
“Isn’t it?” he agreed, lighting a cigarette. “Only a brute would lift his hand against a 108woman. But Burthon’s sister—my wife—had a fiendish temper, and her tantrums aroused all the evil in my nature—there’s plenty there, I assure you. It was the time I choked her that Burthon had me arrested for cruelty. She had put poison in my coffee and I took the fluid into court with me. Burthon said I was lying and I asked him to drink the coffee to establish his sister’s innocence. But he wouldn’t. Pity, wasn’t it? The judge begged my pardon and said I ought to have choked her a moment longer. But no; I’m glad I didn’t, for she died naturally in the end. My dear daughter, whom I sincerely love, is like her lamented mother, except that I can trust her not to poison me.”
“Doesn’t she love you in return?” asked Orissa.
“Sybil? Why, she’s tremendously fond of me. My daughter,” and his voice grew suddenly tender, “has been for years—is now—the only person I live for. We’re chums, we two. The poor child can’t help her inherited tendencies, you know, and I rather enjoy the fact that she keeps me guessing what she’s going to do next. It—er—interests me, so to speak. I like Sybil.”
Sybil interested Orissa, too. Her father’s reports of her were so startlingly condemnatory, and his affection for her so evident, that Orissa’s curiosity was aroused concerning her. Mr. Cumberford, in spit............
