He did not ask her how she had learnt it. “She gave it up when we were married,” he said. “The people she would have to live among would have looked askance at her if they had known. There seemed no reason why they should.” “We ought to be comrades,” answered Joan, with a smile. “I, too, am trying to help the People.”!

He had passed through the swing doors; and they were standing on the pavement waiting for Joan’s bus. “Unless it all comes right in the end,” she added musingly; “and the poor old soul pegs out. I wouldn’t give much for her liver.”

“I shouldn’t have recognized you,” laughed Joan. “What was the occasion?” The medical staff consisted of a Dr. Poujoulet and two assistants. The authorities were always promising to send him more help, but it never arrived. One of the assistants, a Monsieur Dubos, a little man with a remarkably big beard, was a chemist, who, at the outbreak of the war, had been on the verge, as he made sure, of an important discovery in connection with colour photography. Almost the first question he asked Joan was could she speak German. Finding that she could, he had hurried her across the yard into a small hut where patients who had borne their operation successfully awaited their turn to be moved down to one of the convalescent hospitals at the base. Among them was a German prisoner, an elderly man, belonging to the Landwehr; in private life a photographer. He also had been making experiments in the direction of colour photography. Chance had revealed to the two men their common interest, and they had been exchanging notes. The German talked a little French, but not sufficient; and on the day of Joan’s arrival they had reached an impasse that was maddening to both of them. Joan found herself up against technical terms that rendered her task difficult, but fortunately had brought a dictionary with her, and was able to make them understand one another. But she had to be firm with both of them, allowing them only ten minutes together at a time. The little Frenchman would kneel by the bedside, holding the German at an angle where he could talk with least danger to his wound. It seemed that each was the very man the other had been waiting all his life to meet. They shed tears on one another’s neck when they parted, making all arrangements to write to one another. “Dear lad,” said her father, “he would take the most dangerous work that he could find. But I wish he hadn’t been quite so impulsive. He could have been of more use helping me with this War Office contract. I suppose he never got my letter, telling him about it.”
