my companion, gravely; and as he spoke there rushed into the room halt a dozen of the dirtiest and most ragged street Arabs that ever I clapped eyes on.
"'Tention!" cried Holmes, in a sharp tone, and the six dirty little scoundrels stood in a line like so many disreputable statuettes. "In future you shall send up Wiggins alone to report, and the rest of you must wait in the street. Have you found it, Wiggins?"
"No, sir, we hain't," said one of the youths.
"I hardly expected you would. You must keep on until you do. Here are your wages. He handed each of them a shilling. "Now, off you go, and come back with a better report next time."
He waved his hand, and they scampered away downstairs like so many rats, and we heard their shrill voices next moment in the street.

Sherlock Holmes gave a sigh of relief, and relaxed into a smile.
"Take a seat, and try one of these cigars," he said. "We are anxious to know how you managed it. Will you have some whiskey and water?"
"I don't mind if I do," the detective answered. "The tremendous exertions which I have gone through during the last day or two have
