"Weel, now," he said, slowly, "can you no explain matters to me? I am groping about in the dark."

"You shall be told everything," replied Mori.

He speedily placed him in possession of all the facts. Mr. Burr listened to the story without comment. At the conclusion he said, in his quiet way:

"I am no great hand at detective work, but I can see as far thro' a millstone as any mon with twa gude eyes. Mister Grant has been kidnaped, and ye don't need to look farther than the Black's for a clew."

"That is my opinion exactly," exclaimed Nattie.

"I am with you both," said Mori, "but I still insist that we go slow in accusing them. It stands to reason that to make a demand now would warn the conspirators—for such they are—that we suspect them. We must work on the quiet."

"You are right, sir," agreed Mr. Burr.

"What is your plan?" asked Nattie, with natural impatience.

"It is to place Mr. Burr in charge of the business at once, and for us to start forth in search of possible clews. I will try to put a man in the Black residence, and another in his office. We must hire a number of private detectives—I know a dozen—and set them to work scouring the city. The station master, the keeper of every road, the railway guards, all must be closely questioned. And in the meantime, while I am posting Mr. Burr, you must go home and keep as quiet as you can. Remember, excitement will produce inflammation in that shoulder, and inflammation means many days in bed."

The authoritative tone of the young Japanese had its effect. Grumbling at his enforced idleness, Nattie left the office and proceeded to the "bluff." Mori remained at the counting-room, and carefully drilled the Scotchman in the business on hand.
