Indians. Not a sign of them was to be seen anywhere. The only person present with a noticeably dark complexion was a tall man in a pilot coat, and a round hat, who looked like a sailor. Could this be one of them in disguise? Impossible! The man was taller than any of the Indians; and his face, where it was not hidden by a bushy black beard, was twice the breadth of any of their faces at least.
"They must have their spy somewhere," said Mr. Bruff, looking at the dark sailor in his turn. "And he may be the man."
Before he could say more, his coat-tail was respectfully pulled by his attendant sprite with the gooseberry eyes. Mr. Bruff looked where the boy was looking. "Hush!" he said. "Here is Mr. Luker!"
The money-lender came out from the inner regions of the bank, followed by his two guardian policemen in plain clothes.
"Keep your eye on him," whispered Mr. Bruff. "If he passes the Diamond to any body, he will pass it here."

The second man was nowhere to be seen. He looked behind him for his attendant sprite. Gooseberry had disappeared.
"What the devil does it mean?" said Mr. Bruff angrily. "They have both left us at the very time when we want them most."
It came to the turn of the man in the gray suit to transact his business at the counter. He paid in a check—received a receipt for it—and turned to go out.
"What is to be done?" asked Mr. Bruff. "We can't degrade ourselves by following him."
"I can!" I said. "I wouldn't lose sight of that man for ten thousand pounds!"
"In that case," rejoined Mr. Bruff, "I wouldn't lose sight of you, for twice the money. A nice occupation for a man
