“But it still gives us two puzzles to solve,” Al began.
“Well,” corrected Curt, “not two separate puzzles—but a double puzzle, all the same.”
“A double puzzle? I don’t quite see——”
“It’s all one problem,” Bob explained to his younger brother. “But it has two sections. First—was the airplane tampered with as an act against the aircraft corporation or against Mr. Tredway in person?”
“And second?——”
Al did not let Curt complete his deduction. Al had one of his own.
“And second—who did it?”
CHAPTER VI
SUSPICION AND SUSPENSE
Full of their horrifying suspicions, Curt and Bob rode on. Al turned off on a side street to deliver a parcel at the home of his new boss, “Sandy” Jim Bailey, the rigger. Al wanted to “make himself solid” with the sandy-haired man whom he already liked and whose grumbling was over now that he had, as he said, “a willin’ and brainy helper.”
Curt ate lunch with Bob. Both were disappointed when Bob’s mother told them that his father had been called out of town on his case, accepted earlier.
