While Matt was talking, Ferral had got into the car. Matt switched the power into the propeller shaft and the Hawk glided upward. When the car cleared the tops of the trees, Matt brought the air ship to a level.

"Look sharp, Dick," called Matt, his face set and determined. "We've got to win out, this time. If we don't, there's no telling what will happen to the girl. Whipple has already threatened her, in case the officers don't leave the house. Can you see Miss Brady?"

Matt's position, in the rear of the car, rendered it impossible for him to see much of what lay ahead.

"There she is, matey!" cried Ferral. "She sees us coming. There's an open skylight in the roof which shows how she got to the top of the house."

"Any of the men on the roof?"

"No."

"Good! How are we headed?"

"Just right. Hold to the course as you are."

"Are we high enough?"

"Plenty."
