He recalled the night he had caught him examining the device with such care! Jack had since removed it, but in searching in the waste basket for a message discarded by mistake he had since come across what appeared to be crude sketches of the Universal Detector. If Thurman had not drawn them, Jack was at a loss to know who had. But for some mysterious reason he only smiled as he left the wireless room.
"If you've been up to any hocus-pocus business, Mr. Thurman," he said to himself, as he descended to dinner, "you are going to get the surprise of your life within a very short time."
After dinner he came back to the upper deck again, but as he gained it his attention was arrested by the scream of the wireless spark. It was a warm night and the door of the cabin was open. Jack stopped instinctively to listen to the roaring succession of dots and dashes.
"He's calling Washington," said Jack to himself as he listened.
"He's got them," he exclaimed a minute later.
"Hullo! Hullo! I guess I was right in my guess, then, after all. Oh, Thurman, what a young rascal you are."
He listened attentively as Thurman shot out his message to the National Capital. Jack repeated it in an undertone as the spark crackled and squealed.
"Do—I—get—my—reward—right—away?"
Jack actually burst, for some inexplicable reason, into a hearty laugh.
"Oh, Thurman! Thurman!" he exploded to himself. "What a badly fooled young man you are going to be."
