“Then the government has decided to purchase the parachute?”

“It depends upon a final test which is to be held tomorrow.”

“And if it should fail?”

“The test will be successful,” declared the Major confidently. “Bailey Brooks himself is making the jump. But it is a grave matter for the plans to fall into the hands of the enemy.”

Flash fell silent as he thought over what he had learned. He knew that Rascomb had been intensely interested in the Bailey Brooks’ invention. Unquestionably, he had engineered the theft. But it was difficult to understand why the man delayed his get-away now that the plans were in his possession.

Arising abruptly, Flash began to explore the prison room.

“Any chance of getting out of here?”

“None whatsoever,” the Major responded. “There is no window. If we try to break down the door, we’ll only stop a bullet.”

“They’ll probably let us out tomorrow,” Doyle said. “After Rascomb has safely fled the country.”

“And then it will be too late!” Flash exclaimed. “If only we could get out of here tonight! Rascomb might still be captured.”
