“Supposing all this is true,” he said; “what are you going to make out of it?”

“You went there after something the old woman is supposed to have concealed in the den. That is why you searched the walls, George Richmond. Did you do it for your friend, or was it all done on your own hook?”

“For my friend?”

“Yes, for the friend you serve—the money king’s heir.”

At this there was a sudden start, and Richmond looked toward the door.

“You are taking desperate chances in order to keep up your reputation as a detective,” he said at last. “I never thought you would resort to this. I know you. I know that you are Nick Carter, the detective, but with all your shrewdness you can’t hoodwink me.”

With this the speaker moved toward the door and laid his hand upon the knob.

Before Carter could cross the room he saw the door flung open, and the man sprang out into the hall.

The portal was slammed in Carter’s face, and a key turned in the lock.

All this was the work of a second, and he heard the feet of the other on the stairs without.
