The dinner proceeded from course to course. Stewart had never enjoyed a meal more thoroughly. What meal, he asked himself, could possibly be commonplace, shared by such a woman?

The landlady presently dispatched Hans to the station to inquire about the train, while she herself did the serving, and the two women ventured to exchange a few words concerning their instructions. Stewart, listening, caught a glimpse of an intricate system of espionage extending to the very heart of Germany. But he asked no questions; indeed, some instinct held him back from wishing to know more. "Spy" is not a pretty word, nor is a spy's work pretty work; he refused to think of it in connection with the lovely girl opposite him.

"We shall have the police with us soon," said the landlady, in a low tone. "Hans will run at once to tell them of Madame's arrival."

"Why do you keep him?" Stewart asked.

"It is by keeping him that I avert suspicion. If there was anything wrong here, the police tell themselves, this spy of theirs would discover it. Knowing him to be a spy, I am on my guard. Besides, he is very stupid. But there—I will leave you. He may be back at any moment."

He came back just in time to serve the coffee, with the information that their train would not arrive until seven-thirty; then he stood watching them and listening to their talk of home and friends and plans for the future.

Stewart began to be proud of his facility of invention, and of his abilities as an actor. But he had to admit that he was the merest bungler compared with his companion. Her mental quickness dazzled him, her high spirits were far more exhilarating than the wine. He ended by forgetting that he was playing a part. This woman was really his wife, they were going on together——

Suddenly Hans stirred in his corner. Heavy steps were coming toward the court along the sanded floor of the corridor. In a moment three men in spiked helmets stepped out into the fading light of the evening.

"The police to speak to you, sir," said Hans, and Stewart, turning, found himself looking into three faces, in which hostility and suspicion were only too apparent.
