"I want to know how poor Trevanion is getting on have you heard anything?"
"He has been removed to a hospital at C——," replied Proctor; "as you know, he was not well enough to be sent back to England. I'm afraid it will be a long time before he is well again."
"Let's see, who is taking his place?"
"Captain Tremaine. Didn't you know? Promotions are rapid in these days."
"Oh, he has got his captaincy, has he? By the way, there is something else I want to ask you," and Bob, knowing that Proctor had spent some time in Germany, spoke to him in German.
While Proctor was replying, he gave a quick glance at Rivers, and then moved towards him. It was no time for hesitation or parley.
"Rivers," said Bob—"if that is your name—you're a liar. You know German, and, if I'm not mistaken, you're a German spy. At him, Proctor." The last words came out like a shot from a pistol, and he saw Rivers draw a revolver from his pocket as if he intended to shoot him. A few seconds later he was fast bound, and Bob and Proctor escorted Rivers towards General Fortescue's tent.
"General," said Bob, "this man tells me he was sent to me from you; is that true?"
"Heavens, no! I never saw the fellow before, but I am inclined to think we have put our hands upon a spy," he said, when Bob had recorded what had taken place.
Ten minutes later the guilt of the soi-disant Rivers was proved up to the hilt.
