allenged.

"Well, for a starter--"

He paused, for the voice sounded more plainly now, and it said:

"Yes, this is the right place, Mother. Oh, do you think the boys are
here yet?"

"It surely will be a pleasure to meet them again," said another voice,
evidently that of a woman, the other having been a girl's.

"I hope they won't have forgotten us," the girl went on, and at that
Jack could no longer keep quiet. He rushed to the door, opened it, and
cried:

"Bessie! Is that you?"

"Oh, it's Jack! Mother, here's Jack!" cried the girl, and she and her
mother were soon shaking hands with Tom and Jack.

"So, you two were the friends we were soon to see!" exclaimed Tom, as he
placed chairs for Mrs. Gleason and her daughter. Or, to be exact, Tom
placed a chair for the mother, while Jack got one for Bessie.

"Yes, we were told you would be here," said Bessie's mother. "We did not
know you were in Paris until we received word that it would be better
for us to change our lodging and come here."

"But it isn't doing them the military good they thought it would, and,
if all goes well, it may not very long do them any service at all."

"You mean--" began Mrs. Gleason.

But just then Bessie, who had arisen to go to the window to view the
street, turned back with a start, and grasped Jack's hand.

"Look! Look!" she whispered, and through the curtains she pointed to a
man on the opposite side of the way.

"Do you know him?" asked Jack.

"Know him? Yes, to my sorrow."

"Who is it?" asked Tom.

"The spy!" exclaimed Jack. "The man we saw in the train, and the same
fellow who tried to get into our lodgings. In spite of our precautions
he has found out where we are."

"I'm not so sure of that," said Tom. "He may not be here for any
particular purpose. But do you know him too, Bessie?"

"Yes," the girl answered. "He was in the c
