“Well, you were about to say——”

Martin had to put forth a physical effort to regain self-control. He plunged at once into the story of those early years. There was little to tell with regard to Mrs. Saumarez and Angèle. “Fritz Bauer” was the chief personage, and he was now well on his way to a prison camp in England.

Monsieur Duchesne was amused by the map episode in its latest phase.

“And you were so blind that you took no action?” he commented dryly.

“No. We saw, but were invincibly confident. My father sent the map to the Intelligence Department, with which he was connected until 1912, when he was given a command in the North. He and I believe now that someone in Whitehall overlooked the connection between Mrs. Saumarez and an admitted spy. She had left England, and there was so much to do when war broke out.”

The girl married a French officer after the Battle of the Marne, and, as we have every reason to believe, thought she had persuaded her mother to break off relations with her German friends. We know now that the baroness, left to her own devices, adopted a method of conveying information to the Boches which almost defied detection. Owing to her knowledge of the British army she was able to chat with your men on a plane of intimacy which no ordinary woman could command. She found out where certain brigades were stationed and what regiments composed them. She heard to what extent battalions were decimated. She knew what types of guns were in use and what improvements were coming along in caliber and range. She was told when men were suddenly recalled from leave, and where they were going. Need I say what deductions the German Staff could make from such facts?”

“But how on earth could she convey the information in time to be of value?”

“Quite easily. There is one weak spot on our frontier—south of the German line. She wrote to an agent in Pontarlier, and this man transmitted her notes across the Swiss frontier. The rest was simple. She was caught by fate, not by us. Years ago she employed a woman from Tinchebrai as a nurse——”
