At length the clerks began to speak mysteriously of a man who came from time to time to the office, and whose whole manner showed him to possess authority there. The treatment which he received from Henderson—at once cordial and affectionate—showed them to be most intimate and friendly; and from words which were dropped they all thought him to be the senior partner. Yet he appeared to be very little older than Henderson, if as old, and no one even knew his name. If any thing could add to the interest with which the house of Smithers & Co. was regarded it was this impenetrable mystery, which baffled not merely outriders but even the clerks themselves.

Shortly after the departure of Langhetti and Beatrice from Holby two men were seated in the inner parlor of the office of Smithers & Co. One was the man known as Henderson, the other the mysterious senior partner.

They had just come in and letters were lying on the table.

“You’ve got a large number this morning, Frank?” said the senior partner.

“Yes,” said Frank, turning them over; “and here, Louis, is one for you.” He took out a letter from the pile and handed it to Louis. “It’s from your Brandon Hall correspondent,” he added.

Louis sat down and opened it. The letter was as follows:

“August 15, 1840.

“DEAR SIR,—I have had nothing in particular to write since the flight of Miss Potts, except to tell you what they were doing. I have already informed you that they kept three spies at Holby to watch her. One of these returned, as I told you in my last letter, with the information that she had gone to London with a party named Langhetti. Ever since then they have been talking it over, and have come to the conclusion to get a detective and keep him busy watching her with the idea of getting her back, I think. I hope to God they will not get her back. If you take any interest in her, Sir, as you appear to do, I hope you will use your powerful arm to save her. It will be terrible if she has to come back here. She will die, I know. Hoping soon to have something more to communicate,

“I remain, yours respectfully,

“E.L.
