“But how would it help if that did explain the spook tonight? We weren’t flying around the other times!” Chick was unconvinced.
“That’s so!” Toby rubbed his chin. “Besides, how does that work in with this about the mysterious airplane design being found here. Let’s have a look, what do you say?”
Chick uncurled the soggy paper, carefully, on the table.
“In the name of all-possessed! Nobody’d steal that! It don’t mean a thing, does it?”
“Well—only the general body design and strut placement. And I don’t see why they sketched in wings and control surfaces, on a structural skeleton.” Chick was puzzled.
“Hum! You know more about that than I would. Son, it’s a mystery!”
“Is it one mystery—or two?” Very soberly Chick looked up. “Do you see how taking this tracing fits in with the spectre in the sky?”
As Toby shook his head and bent again over the tracery, Chick went on, in the yellow lantern light.
“We thought the haunting might be by some enemy of Don’s uncle, to ruin the airport business,” he argued. “If that is so, then this about the tracing is a different mystery.”
“Gosh-a-mighty! You’re smart for your age!”
