"Did Mr. Mullins say where he was going?" he asked.

"Yes, sir. He said he was going out on an errand."

"Did he take anything with him?"

"I didn't observe, sir."

When Sharpleigh came in a little later he looked about him inquiringly.

"Where's Mullins?"

"I don't think we shall see him again very soon," and the broker told the detective what he knew about his disappearance.

Sharpleigh shrugged his shoulders.

"He has been too sharp for us," he said. "Do you want me to do anything?"

"No; his loss of place and reputation will be a sufficient punishment."

At the close of the day Felix said: "I suppose you don't want me any more."

"You can stay till the end of the week. I have not had time to form any plans."

"Do--do you think Cousin David will come back?"

"I think it very improbable," said the broker, seriously. "Can you throw any light on the events of to-day?"

"Yes, sir."

"Go on. Was the robbery planned?"

"Yes, sir. I was to receive twenty-five dollars for my share."

"I believe you know Chester Rand?"

"Yes, sir."

"Do you know where he lives?"

"Yes, sir."

"Will you ask him to call here to-morrow?"

"I will, sir; but he tells me he has a good place, and would not care to return."

"I am aware of that. It is possible I may retain you----"

"Oh, sir, if you would!"

"On condition that you agree to serve me faithfully."

This was quite beyond the expectations of Felix.

"I will try to do so," he said, earnestly.

"You have begun well by confessing your share in the plot which came so near being successful. As your day's work is ended, I will consider the errand on which I am sending you extra, and will pay you for it."

The broker handed a half dollar to Felix, which he accepted joyfully.

"I don't much care if Cousin David has gone away," he soliloquized.

"Mr. Fairchild seems a good sort of man, and I'll do my best to please him."

When Felix was ushered into Chester's presence the latter was just finishing a comic sketch for _The Phoenix_.

"What's that?" asked Felix, in surprise, for he was quite unaware of Chester's artistic gifts.

Chester showed it to him with a smile.

"Now you see how I am making my living," he said.

"Do you get pay for that?"

"Yes, certainly."

Then Felix bethought himself of his errand.

"There's a great row at the office," he said. "Mr. Fairchild has got home, Cousin David has run away and Mr. Ralston is arrested."

"That's a budget of news. When did Mr. Fairchild return?"

"This forenoon. He wants you to call to-morrow."

"All right. I will do so."

"And if he offers you back your old place you won't take it?" said Felix, anxiously. "If you don't, I think he'll keep me."

"Then I'll promise not to accept. I am better satisfied where I am.

Have you had supper, Felix?"

"No."

"Then come and take supper with me. I go out about this time."

"It had certainly been a day of surprises," as Felix reflected when he found himself seated opposite a boy whom he had always disliked, as his guest.
