A different door opened and four Chinamen came out. They shuffled along the corridor, talking, and entered at still a different door.
At the same time five others came out of that door and for fully ten minutes stood talking in the corridor, vanishing at last through the door out of which the others came.
Again Old King Brady thought he had got his chance, but once more he was balked in the same way.
At last his chance really did come and finding that they had the corridor to themselves he and Leggett pushed on.
Now at the start the old detective had been at particular pains to identify that door.
But did he still remember it? was the question.
He could not feel by any means certain and the worst of it was a quick decision was absolutely necessary.
"I think this is it," he said, pausing before a certain door.
"You want to be sure," replied Leggett.
"I am as sure as I can be. Yes. I think this is it."
