“I shall not rest until I have satisfied myself on several points that have a direct bearing on the mystery. I am in hopes that when I have done that, I shall have a report for you that will be valuable. I cannot say any more than that at this stage. I will call you up as soon as I have something to communicate. Meanwhile, I should advise you not to walk about the streets or go into public places much.”

“I never do, for that matter,” replied Bentham. “You think some of the Yellow Tong might get after me personally then, do you?”

“Have you a gun?”

“Yes. I got a permit to keep one in the house and to carry it, some time ago, when these burglaries began. Look!”

He showed a serviceable-looking automatic pistol in the table drawer, in a chamois bag. Nick saw that it was well supplied with cartridges and ready for instant use.

“That’s well,” said the detective. “If any of the tong should find their way to you and ask insolent questions, or if you should see any suspicious movements on the part of any burglar, I should advise that you shoot first and ask questions afterward.”

Before Matthew Bentham could comment on this emphatic advice, Chick came into the room and showed, in a way that Nick Carter understood—although it meant nothing to Bentham—that he had something weighty to communicate.

The detective arose and nodded carelessly to Chick.

“Ready to go, eh, Chick? I was just saying ‘good morning’ to Mr. Bentham.”

“Did you find anything from Swagara?” asked Bentham, in a tone that told plainly enough how surprised he would have been if the answer had been in the affirmative.
