In vain Harry pleaded. Now that he knew that Graves had used his credentials from Colonel Throckmorton, he decided that it would be foolish to claim his own identity. Graves had assumed that, and he had had the practically conclusive advantage of striking the first blow. So Harry decided to submit to the inevitable with the best grace he could muster.
"All right," he said. "I'll go along with you, officer. But you'll be sorry before it's over!"
"Maybe, sir," said the policeman. "But orders is orders, sir, and I've got to obey them. Not that I likes running a young gentleman like yourself in. But—"
"Oh, I know you're only doing your duty, as you see it, officer," he said. "Can't be helped—but I'm sorry. It's likely to cause a lot of trouble."
So he surrendered. But, even while he was doing so, he was planning to escape from custody.

A GOOD WITNESS
Dick's surprise and concern when he found the cache empty and deserted, with papers and motorcycles alike gone, may be imagined. For a moment he thought he must be mistaken; that, after all, he had come to the wrong place. But a quick search of the ground with his flashlight showed him that he had come to the right spot. He could see the tracks made by the wheels of the machine; he could see, also, evidences of the brief struggle between Harry and Graves. For a moment his mystification continued. But then, with a low laugh, Jack Young emerged from the cover in which he had been hiding.
