CHAPTER VII.—A KEY WITH A BROKEN STEM.

The lights were burning low in a bachelor flat on a noisy street corner in the city of San Francisco, and a man of perhaps thirty lay on a couch with his eyes closed. There were in this sitting room, which faced one of the noisy streets, a grand piano, a costly music cabinet, a walnut bookcase filled with expensively bound volumes, numerous lazy chairs of leather, and the rug on the polished floor was rich and soft. The occupant of the flat evidently enjoyed luxurious things and had the money to pay for them.

When a clock in a distant steeple struck midnight there came a knock at the locked door in the main corridor which connected with the private hallway on which the flat opened. A Japanese servant, small, obsequious, keen-eyed, opened the door, after the hesitation of a moment, and peeked out. He would have closed it again instantly, seeing a stranger there, only Ned Nestor, who had anticipated some action of the kind, thrust a shoe into the opening, and, reaching in, unfastened the chain.

“I wish to see Mr. Albert Lemon,” he said.

The Jap tried to force the door back and lock it, but was unsuccessful.

“No savvy!” he cried, as Ned brushed past him and stood in the private hall.

Ned paid no further attention to him, but entered the sitting room and at once advanced to the couch where the man lay. The figure on the couch did not move, but the Jap forced himself in the boy’s way with his cry of “no savvy!”

“Opium?” Ned asked, pointing down to the man.

“No savvy!”

“Hit the pipe?” he asked, putting the question in a new way.
