“But he looks like a German; and his name!”

“Ah, he is from Alsace.  But not a German!” said the waiter, absolutely whitening with indignation.  “He was at Belfort.  So was I. Mon Dieu!  No, a thousand times no!”

“But has he been living here long?” said the consul.

“In Paris, a few months.  But his Department, M’sieur understands, takes him everywhere!  Everywhere where he can gain information.”

The consul’s eyes were still on the Captain Christian.  Presently the officer, perhaps instinctively conscious of the scrutiny, looked towards him.  Their eyes met.  To the consul’s surprise, the ci-devant Karl beamed upon him, and advanced with outstretched hand.

But the consul stiffened slightly, and remained so with his glass in his hand.  At which Captain Christian brought his own easily to a military salute, and said politely:—­

“Monsieur le Consul has been promoted from his post.  Permit me to congratulate him.”

“You have heard, then?” said the consul dryly.

“Otherwise I should not presume.  For our Department makes it a business—­in Monsieur le Consul’s case it becomes a pleasure—­to know everything.”

“Did your Department know that the real Karl Schwartz has returned?” said the consul dryly.

Captain Christian shrugged his shoulders.  “Then it appears that the sham Karl died none too soon,” he said lightly.  “And yet”—­he bent his eyes with mischievous reproach upon the consul.

“Yet what?” demanded the consul sternly.

“Monsieur le Consul might have saved the unfortunate man by accepting him as an American citizen and not helping to force him into the German service.”

The consul saw in a flash the full military significance of this logic, and could not repress a smile.  At which Captain Christian dropped easily into a chair beside him, and as easily into broken German English:—­

“Und,” he went on, “dees town—­dees Schlachtstadt is fine town, eh?  Fine womens?  Goot men?  Und peer and sausage?  Blenty to eat and trink, eh?  Und you und te poys haf a gay times?”

The consul tried to recover his dignity.  The waiter behind him, recognizing only the delightful mimicry of this adorable officer, was in fits of laughter.  Nevertheless, the consul managed to say dryly:—­

“And the barracks, the magazines, the commissariat, the details, the reserves of Schlachtstadt were very interesting?”

“Assuredly.”

“And Rheinfestung—­its plans—­its details, even its dangerous foundations by the river—­they were to a soldier singularly instructive?”

“You have reason to say so,” said Captain Christian, curling his little mustache.

“And the fortress—­you think?”

“Imprenable!  Mais”—­

The consul remembered General Adlerkreutz’s “Zo-o,” and wondered.
