f ordinary appearance,
busy with their meal. Beyond them was an American soldier, who
seemed to have dropped in out of curiosity. He was paying very
little attention to his meal, but was eyeing a young woman who
was seated behind the cash counter.

On the other side of the room, and partially hidden from our boys
by the cash counter, was another man, smoking, and evidently
waiting for some one. He kept his eye on the door and every once
in a while glanced nervously at his watch.

"Not much going on in here," said Donald in English.

"No; but we are a little early. There may be more in before we
finish our breakfast."

It was a true prediction, for within the next five minutes as
many more persons entered and disposed themselves around the
various tables. Then the boys' breakfast was served and for a few
minutes they were more absorbed in the food than in the guests.

As Donald raised his eyes for a moment, however, he caught sight
of a man talking to the one sitting back of the cash counter.
They were evidently arguing about something in an undertone and a
minute later the newcomer took a seat with his back to the boys.

"Look!" was Donald's smothered exclamation, "over there by the

keeping away from us, he will leave. If he is not, he may come
over and speak to us. There is no reason why he should not, so
far as he knows."

"How would it do to make ourselves visible?"

"I hardly know." Then after a pause: "I'll tell you what. As soon
as we finish we'll go out, as though we did not see him, but we
will be sure to make enough commotion to attract his attention.
Then we'll station ourselves where we can see him as he comes
out."

"That's all right, Don; but suppose he doesn't come out?"

Donald scratched his head.

"Oh!" he exclaimed, "I knew I had a thought back of that. When he
sees us, if he is not trying to avoid us, he will speak to us. If
he does not speak to us, we will know there is something wrong
and take immediate steps to have him arrested."

"But he may escape."

"How can he?"

"I suppose he could
