Then a soldier deposited at the officer's feet the bag full of fish, which he had taken care to bring away. The Prussian smiled.

“Not bad, I see. But we have something else to talk about. Listen to me, and don't be alarmed:

“You must know that, in my eyes, you are two spies sent to reconnoitre me and my movements. Naturally, I capture you and I shoot you. You pretended to be fishing, the better to disguise your real errand. You have fallen into my hands, and must take the consequences. Such is war.

“But as you came here through the outposts you must have a password for your return. Tell me that password and I will let you go.”

The two friends, pale as death, stood silently side by side, a slight fluttering of the hands alone betraying their emotion.

“No one will ever know,” continued the officer. “You will return peacefully to your homes, and the secret will disappear with you. If you refuse, it means death-instant death. Choose!”

They stood motionless, and did not open their lips.

The Prussian, perfectly calm, went on, with hand outstretched toward the river:

“Just think that in five minutes you will be at the bottom of that water. In five minutes! You have relations, I presume?”

Mont-Valerien still thundered.
