“Monsieur,” he said, “I listen to you eagerly, and yet I am puzzled. You wear the uniform of an English officer, but you come to me, is it not so, as an emissary of Germany?”

“In bald words that may be true,” Granet confessed, “yet I would remind you of two things. First, that the more dominant part of the personality which I have inherited comes to me from Alsatian ancestors; and secondly, that this peace for which I am striving may in the end mean salvation for England, too.”

“I hear you with relief,” Monsieur Guillot admitted. “In this transaction it is my great desire to deal with a man of honour. As such I know perceive that I can recognise you, monsieur.”

Granet bowed gravely and without any shadow of embarrassment.

“That assuredly, Monsieur Guillot,” he said. “Shall I proceed?”

“By all means.”

Granet drew a thin packet from the breast pocket of his coat. He laid it on the table between them.

“I received this,” he announced, “less than three weeks ago from the hands of the Kaiser himself.”

Monsieur Guillot gazed at his companion incredulously.

“It was very simple,” Granet continued. “I was taken prisoner near the village of Ossray. I was conducted at once to headquarters and taken by motor-car to a certain fortified place which I will not specify, but which was at that time the headquarters of the German Staff. I received this document there in the way I have told you. I was then assisted, after some very remarkable adventures, to rejoin my regiment. You can open that document, Monsieur Guillot. It is addressed to you. Guard it carefully, though, for it is signed by the Kaiser himself. I have carried it with me now for more than a fortnight in the inner sole of my shoe. As you can imagine, its discovery upon my person would have meant instant death.”
