“See how queer he’s acting,” he whispered. “And he isn’t eating much of anything; I’ve been watching him. Look, he doesn’t even know that his fork is empty!”

It would have been very evident to a much less careful observer than a detective that Dick was absent-minded and preoccupied that evening. Once he laid down his fork and began tracing patterns on the table-cloth with his thumb nail and several times he paused with his glass of milk in mid-air to gaze frowningly into space.

“I’ll bet he’s thinking up some scheme to get that money,” said Chub, after a few moments of amused observation. But Roy shook his head.

“I don’t think it’s that,” he answered. “He wouldn’t have to run away out of sight every day to just think. He’s doing something; you see if he isn’t.”

“Well, he can just go ahead and do it for all I care,” said Chub. “I’m not going to stand around in the snow to-night, I’ll tell you that.”

“Nor I,” replied Roy. “Besides, to-morrow will be the time to play detective. We won’t have anything to do in the morning, Chub, so let’s track him. Even if we don’t find out anything it will make him peeved.”

“I didn’t notice that he got much peeved last night,” observed Chub dryly.

“Never mind; he won’t get away from us in daylight as easily as he did then,” responded Roy. “And whatever he’s up to he will be sure to try and sneak off in the morning. So let’s watch him, eh?”

“All right; Vidocq again takes up the relentless pursuit.”

“What we need,” said Roy, “is a clue. Every detective ought to have a clue.”
