only
knew German, I would be a match for 'em. I suppose you do not happen
to know German?"

Bob did not reply, but he looked at the other keenly, noticing his
fair, smooth, ruddy face and altogether innocent appearance. Then a
suspicion was born in his mind. "Wait a minute, will you?" he said,
and then, calling a soldier, told him to fetch Lieutenant Proctor, as
he wished to speak to him.

"What's up, Nancarrow?" said Proctor, when he came.

"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

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.

Notes were found on his person proving not only the fact that he had
come from the German lines, but that he had for some time been
gathering information in the British lines, with the evident intention
of conveying it to the enemy.

This information, moreover, was of such vital import, and it had been
kept with such secrecy, that it seemed miraculous that he could have
obtained it; still, obtained it he had, and a dozen proofs of his
treachery were found upon him. To all questions, however, he
maintained a rigid silence; evidently he was faithful to his own
country.
