"Julie and Suzanne," said Lannes, "are going tomorrow with other nurses to the little town of Ménouville, where also many wounded lie. They are less well supplied with doctors and nurses than we are here. Dr. Delorme goes also with a small detachment as escort. I have asked that you, Monsieur Jean the Scott, be sent with them. Our brave Picard goes too. Ménouville is about eight miles from here, and it's not much out of the way to the front. So you will not be kept long from your Strangers, John."
"I go willingly," said John, "and I'm glad, Philip, that you've seen fit to consider me worth while as a part of the escort."
He spoke quietly, but his glance wandered to Julie Lannes. It may have been a chance, but hers turned toward him at the same time, and the eyes, the blue and the gray, met. Again the girl's brilliant color deepened a little, and she looked quickly away. Only the watchful and grim Suzanne saw.
"Do you have to go away at once, Philip?" asked Julie.
"In one hour, my sister. There is not much rest for the Arrow and me these days, but they are such days as happen perhaps only once in a thousand years, and one must do his best to be worthy. I'm not preaching, little sister, don't think that, but I must answer to every call."
The twilight had spread from east to west. The heavy shadows in the east promised a dark night, but out of the shadows, as always, came that sullen mutter of the ruthless guns. Julie shivered a little, and glanced at the dim sky.
"Must you go up there in the cold dark?" she said. "It's like leaving the world. It's dangerous enough in the day, but you have a bright sky then. In the night it's terrible!"
"Don't you fear for me, little sister," said Lannes. "Why, I like the night for some reasons. You can slip by your enemies in the dark, and if you're flying low the cannon don't have half the chance at you. Besides, I've the air over these regions all mapped and graded now. I know all the roads and paths, the meeting places of the clouds, points suitable for ambush, aerial fields, meadows and forests. Oh, it's home up there! Don't you worry, and do you write, too, to Madame, my mother, in Paris, that I'm perfectly safe."
Lannes kissed her and went away abruptly. John was sure that an attempt to hide emotion caused his brusque departure.
"Believe everything he tells you, Mademoiselle Julie," he said. "I've come to the conclusion that nothing can ever trap your brother. Besides courage and skill he has luck. The stars always shine for him."
