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.
