Then it began to dawn on Matt that the schemers had fallen back on Hooligan.

"They've gone——"

"You're quick at a guess, now I've dropped the hint," interrupted Brady. "Yes, they've gone to the house where Hooligan is acting as caretaker. The family's away for the summer, and Hooligan is able to do about as he pleases there. It's a mansion, and a fine one, but it's a safe bet that the Hooligans won't be taking care of the place another year. The family's abroad, I understand, and they wouldn't feel very easy if they knew what sort of a gang was staying in the place."

"Where's the house?" went on Matt, his excitement growing.

"It's a big, flat-topped mansion close to the river, just below the town. It's owned by a man named Caspar——"

"I know the place!" exclaimed Graydon. "I've seen it a dozen times. It stands at a good distance from any other house, and is one of the show places of River Forest. You're right, Brady. Mr. Caspar would be mightily put out if he knew how his home was being used."

"Well, that's where Pete and Whipple, two of my old gang, have taken my daughter," went on Brady. "They're there now, and so are the Hooligans. But there's no telling how long they'll be there. It's up to you officers to get busy and make the most of my tip. I want you to capture those two traitors who have been trying to cheat me out of the stuff I stole, and have cached away—and who are trying to make my daughter help them. I want you to rescue the girl. That's your part of the bargain, Matt," he added, turning to the young motorist. "I don't care what's done with the Hooligans, for they don't concern me, but I want to see Pete and Whipple at hard labor alongside of me in the 'pen,' and every time they look at me I want them to remember that it was Brady who put them where they are!"

A look of demoniacal hate convulsed Brady's face. If any one had doubted the genuineness of his desire for revenge upon Pete and Whipple, that look would have settled it.

"We'll get them," averred Graydon, "but first we'll make sure of you."

He stepped forward with the handcuffs, and Brady put out his wrists.
