“I certainly do.”

“If that is the case, it ought not to be hard to get at the secret of Mr. Anderton’s death.”

Nick Carter smiled slightly and shook his head.

“My dear Chick, don’t jump hastily to conclusions. What evidence have we got against Professor Tolo?”

“Plenty, I should think. Wasn’t he snooping about in this room when we came back to it, after going downstairs to see a man who had disappeared when we got there? Then, doesn’t he hide his face with those big spectacles? And wasn’t I following him when I was sandbagged and struck at with the crossed needles?”

“All that is suspicious, but not proof, Chick.”

“Do we know where he lives?”

“That is easily found out,” replied Carter. “But even then, we shall have to learn a great deal more before we can show that he is associated with the Yellow Tong.”

“But you believe he is, don’t you?”

“I do. Only we haven’t anything conclusive with which to back up that belief—yet. For the present, I want to find out how the person who killed Andrew Anderton got into this room. When I have reached that point, I shall have something from which to start on other inquiries. It would give us a base of operations.”
