"Dear Sir—I believe that I am on the right track, and all through the clue supplied by yourself. Please aid me a little further. I would like to know the exact size of the missing girl. As a physician, you will supply this even better than the father. Also inform me of any mark or peculiarity by which I might recognize her, alive or dead. Please answer at once.

"Yours truly,

"J. Barnes."

This he sent by a messenger, and received the following in reply:

"Mr. Barnes:—

"Dear Sir—I hope you will succeed. Elinora is small and slim, being rather undersized for her age. I should say about four feet ten inches, or thereabout. I know of no distinctive mark whereby her body could be recognized, and hope that nothing of the sort seemingly suggested may be necessary.

"Yours truly,

"Robert Donaldson, M.D."

Mr. Barnes read this, and appeared more pleased than its contents seemed to authorize. At the appointed time he went to the Hoffman House. He found Mr. Gedney impatiently walking up and down the lobby.

"Mr. Gedney," said he, "at the beginning of this case you offered me my own price for recovering your daughter. Now, supposing that you pay this ransom, it would appear that you would have had little need of my services. If, however, I get your daughter, and save you the necessity of paying any ransom at all, I suppose you will admit that I have earned my reward?"
