"All we know is that he is tall, has light brown hair, and is very strong," Ned replied. "But there are ten thousand people in New York this minute who answer to that description."

"How do you know he is tall?" demanded Jack.

"When he lay on the rug," Ned explained, "he stretched out on his stomach to look through the hole, if he could. He couldn't; he could only listen, for the cut was made so as to be hidden by the ornamental brass piece that circles the rod from which the chandelier swings. The marks of his elbows and toes were on the soft fiber of the rug, showing him to be a man at least six feet tall."

Ned walked over to the large box again and bent over it.

"Crumbs!" he exclaimed, in a second. "Crumbs!"

"Then he must have brought a lunch up with him," Jack exclaimed excitedly. "There is no knowing how long he was here!"

"Some one in Washington has leaked!" Ned declared, angrily.

"Why Washington?" demanded Jack. "Why not New York?"

"Because no one in this city knows about our being engaged to hunt down the abductor. My instructions have all come in cypher, and some of them have, as you know, been addressed to this house. And there you are!"

Chang Chu arose limply, rubbing a small wound in his head from which blood had come, and tottered off toward the staircase. As he did so, Ned noticed that his pigtail was very black, very long, and very greasy.
