“I’ll help,” said Olive, briskly. “I refuse to believe any harm has come to him. Let’s call up his clubs.”

“I’ve done that,” said Talcott. “I can’t think he went away anywhere—willingly.”

“How, then?” cried Olive. “Oh, wait a minute,—I know something!”

“What?” asked Talcott and I together, for the girl’s face glowed with her sudden happy thought.

“Why, Uncle Amos has a private elevator of his own. He went down in that!”

“Where is it?” asked Manning.

“I don’t know,” and Olive looked about the room. “And Uncle forbade me ever to mention it,—but this is an emergency, isn’t it? and I’m justified,—don’t you think?”

“Yes,” said Manning; “tell all you know.”

“But that’s all I do know. There is a secret elevator that nobody knows about. Surely you can find it.”

“Surely we can!” said I, and jumping up, I began the search.
