"Well, that's so. It might work out to the good," replied the wardman. "Anyhow it seems to be our only chance." "It does, and we will try it," replied the old detective. "And now let us pull out." Old King Brady and Alice went to the office thinking it barely possible that Harry might have escaped and gone there. Failing here they went home to supper and at eight o'clock turned up at the Pell street room again. There was nothing to be found here either, so they waited until Wardman Connors came and then went around on Mott street. The wardman stepped in first. It had been arranged that if he found anyone in the room he should come back and inform them; otherwise he was to wait there till they came up. Giving the man ten minutes, Old King Brady and Alice went up stairs. Mr. Connors heard them coming and opened the door for them. "No one here?" questioned Old King Brady. "No one." "Is the corpse still fastened to the rope?" "Sure thing. I didn't attempt to pull it up.'" It was getting dark. Old King Brady and the wardman pulled on the rope and brought up old Fen Wix again. The body was again lowered and Old King Brady and Alice, along with the wardman, took up their stations in the smaller room. A tedious wait followed, but along towards nine o'clock the patience of the detectives was rewarded by hearing someone enter the other room. They had left the door slightly ajar and Old King Brady peered through the opening. A Chinaman in native dress stood there in the dark. Old King Brady drew his revolver ready for business. He was not called upon to act, however. The man went to the other side of the chimney, which Old King Brady had examined with the greatest care. For a moment he stood there and then he vanished. Unfortunately as he vanished the old detective could not see just what the fellow did. "Hush!" breathed Alice as he was about to step out into the other room. "Someone else coming, I think." But it proved to be only some person passing the door on their way to the floor above. They went outside after the alarm had passed and again Old King Brady examined that particular piece of wall. And this time he found it. The arrangement was very peculiar, but Old King Brady mastered the mystery and the opening stood revealed. Behind the panel there was a very narrow flight of stairs leading down. Old King Brady immediately started to descend, flashing his light ahead of him. They followed him down into the place to which Harry had been taken. There in the niche stood the corpse of the informer, silent and quiet. Following the passage for a short distance they came upon two inner doors, both set at an angle. "Which den do you propose to tackle first?" questioned Connors. "To the right is always my rule, unless I have reason to change it," replied the old detective. "To the right it is then," said the wardman. He tried the door, to find it locked. So was the door on the left.
