On the following afternoon an old farmer with a homespun suit, an old felt hat, and gray whiskers, arrived at the hotel.
Harry was standing in the lobby when he came in and recognized him at once as Old King Brady, but made no sign.
The old detective recognized the boy at the same moment, and calling for a room, he seized his carpet bag and umbrella, and followed the bell-boy upstairs.
Harry considered it safest to keep apart from his partner in public, and for that reason failed to speak to him.
When he afterward learned which room Old King Brady occupied, he quietly went up there and was admitted.
In whispers they explained to each other all that transpired and the old detective was delighted over the boy's success.
"So the mysterious woman in black was the girl smuggler, eh?" asked the old detective. "Well, I'm surprised."
"Her warning you, shows that she has some regard for us and don't wish to see us come to grief," replied Harry, sentimentally.
"On the other hand, it may have been a diplomatic move on her part to bluff us off until they smuggle that big consignment of diamonds over the border," replied Old King Brady, practically.
"Well, she didn't succeed."
