"By Jove!" said Chester. "I hadn't thought of that. So that was it, eh?"
"Yes, that was it," said the girl.
The Canadians now were introduced around, after which the young girl said.
"Come. I may as well show you to your hiding places. It is as well for you to be there as here. There is no telling when some of the Germans may arrive."
"But aren't you afraid to be among them alone?" asked Hal.
"Pshaw!" exclaimed the girl. "Who would hurt a harmless old woman?"
She led the way into the room beyond, walked across and pressed a hidden spring in the side of the wall. Instantly a secret door moved open.
"It can be opened from within as well," said the girl. "You may have a light here if you wish. The door is so constructed that the rays cannot be seen from without. I shall leave you now. My only injunction is, do not talk too loud. I'll bring you food and water in the morning."
She bade them good-night and took her leave.
The friends talked in low tones for some moments, then stretched out on the floor and soon were fast asleep.
