staring down at the forward promenade, yesterday afternoon, when I
saw you walking with a tall young fellow, who seemed exceedingly
interested in you. Naturally, I was a little curious, as he happened to
be a second-class passenger like myself...."

"Second-class!" broke in Kasia, and stopped herself.

"Did you think him a millionaire?" queried Dan, a little bitterly.

"No," answered Kasia, quietly; "I thought him just what he is--an
ingenuous young German, not very brilliant, perhaps, but clean and
honest. I passed a very pleasant half hour with him."

Dan's face was a little pale, but he looked at her manfully and squared
his shoulders.

"I deserved that!" he said. "Thank you, Miss Vard. But it _was_ very
lonely, last night!"

Kasia's look softened.

"Yes," she agreed; "it was."

"You felt it, too?" asked Dan, his face lighting up again.

"Certainly I felt it. I haven't dared make any friends among the
first-class passengers, and a person can't read _all_ the time! One
likes to talk occasionally, no matter with whom."

"Why not slip over to second-class to-night," Dan suggested, "and sit on
the bench. The moon is very beautiful."

But Kasia shook her head, smiling.

"I shall have to admire it alone," she said. "We must not be seen so
much together--it is not wise for us to sit here. Suppose some one,
seeing us together, should take it into his mind to search your baggage,
and should find that little package...."

"He wouldn't find it," Dan broke in. "During the day, I carry it in my
pocket. At night, I sleep with it under my pillow."

Kasia gave him a quick glance.

"That is splendid!" she said, quickly. "And you don't even wish to know
what it is?"

"Not unless you wish to tell me. There is one danger, though. If the
customs inspector should happen to run across it, he will want to know
what it is."

"Tell him it is an electrical device."

"And if he opens it?"

"That will do no harm. All he will find is a small metal box, filled
with tiny wires coiled about each other."

Dan breathed more freely.

"That simplifies things," he said. "From what you said when you gave it
to me, I was afraid I might have to knock him down, snatch the package,
and make a break for it."

"No," and Kasia smiled. "It would appear of value only to some one who
knew what it was. The customs inspector doesn't count."

"And to-morrow evening, say at eight o'clock, I shall bring it up to
you."

"Very well. I sha
