"That's the least of it," said Matt gravely. "Miss Brady saved Ferral's life and mine, at the time of that balloon-house plot of yours, Brady. You want to take the Hawk to the place in La Grange where Hooligan and his wife live?"

"To the place where they live when they're at home," answered Brady. "They only stay there in the winter. During the summer they're taking care of that house in River Forest."

"They're making fine use of that River Forest house!" exclaimed Matt. "But they can't be there now, if they've got Helen at the place in La Grange."

"Mrs. Hooligan has charge of Helen, and Whipple and Pete are there with her. Hooligan himself is at River Forest."

"What sort of a two-faced scoundrel is this Hooligan, that he helps criminals in such work?"

"He happens to be Pete's brother."

"That doesn't excuse him."

"Probably he's figuring on getting a share of the stuff Pete and Whipple are hoping to find. There's enough of the loot to make them all pretty comfortable. If you hadn't butted into my affairs, King, I could have sailed away in the Hawk and taken life easy for the rest of my days."

"The proper way to work this," said Matt, after a moment's reflection, "is to take you to South Chicago, Brady, leave you there, and pick up Harris and two other officers. Then you can tell us where to go and we'll have Whipple, Pete and the two Hooligans behind the bars before daylight. And Miss Brady will be safely rescued."

"That won't do at all," protested Brady. "In the first place, that will make too much of a delay at a time when every moment may count; and, in the next place, I'll have to be along to tell you where to moor the air ship and point out the house."
