hateau where mother and I were
held prisoners by Potzfeldt. He is a tool in the pay of that spy, and a
spy himself!"

"Then we ought to do something!" exclaimed Jack, and he started to rush
from the room.

CHAPTER XIV

WITH COMRADES AGAIN

"Hold on! Wait a minute!" exclaimed Tom, as he caught hold of his chum.
"Where are you going?"

"Out to give warning to a policeman or to some army officer about that
spy!" exclaimed Jack. "We know him to be such, and now, with Bessie's
word that he was with Potzfeldt, it's enough to cause his arrest."

"Yes, maybe it is," agreed Tom, who was a bit more cautious than his
impetuous chum. "But if we do that we may spoil the plans of Major de
Trouville. Better let matters take their course, Jack. That spy may not
know we are here, and again, he may. But if he doesn't, rushing out now
would be sure to give the secret away. As it is, there is a chance we
may keep it."

Jack, caught midway in his impetuous rush from the room, stood
reflectively. What Tom had said to him appeared to make an impression.
Then Bessie added her words of advice.

"Yes, Jack," she said, "I think it would be rather rash to go out now
and confront that man, or start a chase after him. I know I'm not as
experienced as you two famous birdmen," she went on with a smile, "but
I've been through some terrible experiences, as almost every girl has in
this war zone, and I can do more thinking than I used to. Don't you
think it would be wise to wait, Mother?"

"Yes, Bessie," answered Mrs. Gleason, "I do. Our good friends in the
military service who told us to come here, must have had some object.
Perhaps it was connected with this same man who was so unkind to us in
the chateau, and who was certainly a tool of that man I trusted once,
but never will again--Carl Potzfeldt!" and she shuddered as she thought
of what she had gone through.

"Let him go," she said to Jack. "Perhaps it is just a coincidence that
he is passing just as we arrive. Our departure from our last lodgings
was made secretly."

"So was ours," said Tom. "And yet I don't see how that spy found us so
soon."

"It is that which makes me think it is accidental," observed Mrs.
Gleason. "It would be very unwise now to go out, I think."

"All right, then I'll stay in," said Jack with a smile. "Especially as I
have such good company. Tell me," he went on, "are you and your mother
going to board here?" he asked Bessie.

"Yes," answered Mrs.
