“You are still after the trio?”

“Yes.”

“You can’t seem to find a clew as to their whereabouts?”

“Not the slightest.”

“Well,” said the chief, slowly, “yesterday we brought a man in here from Chinatown. He killed a man in an opium den.

“While questioning him closely I learned that he knew Dan Collins.”

“Dan Collins!” exclaimed Harry.

“Yes. Do you know him?”

“He is one of the trio!”

“Ah! Then it is all right. Collins and two companions have been frequenting Ah Ling’s place in Mott street for a few days past.”
