of the theft?"

"I know pretty well who robbed me," returned Mr. Waterbury, and he
suffered his glance to rest on Graham, who seemed in a hurry to get
away.

"Come along, Vincent," he said sharply.

Vincent obeyed. Light dawned upon him, and he determined to verify his
suspicions.

"Graham," said he, in a low voice, "you did this."

"Did what?"

"You got that wallet."

Graham concluded that he might as well make a clean breast of it, since
it had become a matter of necessity.

"Well," said he, "suppose I did?"

"You were not going to let me know of it," said Vincent suspiciously.

"That is true. I was ashamed of having been imposed upon."

"When did you find out that the money was bogus?"

"Immediately."

"If it had been good, would you have shared with me honorably?"

"Of course. What do you take me for?"

Vincent was silent. He did not believe his companion. He suspected that
the latter had intended to steal a march on him.

"You might have told me of it," he continued, in a tone of
dissatisfaction.

"There was no need to say anything, as there was nothing to divide."

"Have you got the wallet with you now?"

"No; I threw it overboard."

"And the bills?"

"You may have them all, if you like."

"Come into the stateroom, where we can be unobserved, and show them to
me."

Graham complied with his suggestion.

"It would have been a good haul if they had been genuine," said Vincent,
as he unfolded the roll.

"Yes, but they are not; worse luck!"

"I didn't give the old fellow credit for being so sharp."

"Nor I. There's more in him than I supposed there was."

"Well, what is to be done?"

"Nothing. The old man is on his guard, and, besides, he suspects me. He
was probably awake when I entered the stateroom. He and the boy have
probably laughed over it together. I hate that boy."

"Why?"

"Because he is a green country boy, and yet he has succeeded in
thwarting me. I am ashamed whenever I think of it."

"Would you like to play a trick on him in turn?"

"Yes."

"Then give me this roll of bills."

"What do you want to do with them?"

"Put them in his pocket."

"Can you do it unobserved?"

"Yes. The fact is, Graham, I served an apprenticeship as a pickpocket,
and flatter myself I still have some dexterity in that line."

"Very well, it will be some satisfaction, and if the old man didn't see
me enter the stateroom, he may be brought to believe that the boy robbed
him. If th
