on't know."

"Why, hasn't she left her new address?"

"No. The footman came for letters several times."

No information was to be got here, and Mr. Penfold and Nancy Rouse went
home greatly disappointed, and puzzled what to do.

At first sight it might appear easy for Mr. Penfold to learn the new
address of Miss Rolleston. He had only to ask Arthur Wardlaw. But, to
tell the truth, during the last fortnight Nancy Rouse had impressed her
views steadily and persistently on his mind, and he had also made a
discovery that co-operated with her influence and arguments to undermine
his confidence in his employer. What that discovery was we must leave him
to relate.

Looking, then, at matters with a less unsuspicious eye than heretofore,
he could not help observing that Arthur Wardlaw never put into the office
letter-box a single letter for his sweetheart. "He must write to her,"
thought Michael; "but I am not to know her address. Suppose, after all,
he did intercept that letter."

And now, like other simple, credulous men whose confidence has been
shaken, he was literally brimful of suspicions, some of them reasonable,
some of them rather absurd.

He had too little art to conceal his change of mind; and so, very soon
after his vain attempt to see Helen Rolleston at the inn, he was bundled
off to Scotland on business of the office.

Nancy missed him sorely. She felt quite alone in the world. She managed
to get through the day--work helped her; but at night she sat
disconsolate and bewildered, and she was now beginning to doubt her own
theory. For certainly, if all that money had been Joe Wylie's, he would
hardly have left the country without it.

Now, the second evening after Michael's departure, she was seated in his
room, brooding, when suddenly she heard a peculiar knocking next door.

She listened a little while, and then stole softly downstairs to her own
little room.

Her suspicions were correct. It was the same sort of knocking that had
preceded the phenomenon of the hand and bank-notes. She peeped into the
kitchen and whispered, "Jenny--Polly--come here."

A stout washerwoman and the mite of a servant came, wondering.

"Now you stand there," said Nancy, "and do as I bid you. Hold your
tongues, now. I know all about it."

The myrmidons stood silent, but with panting bosoms; for the mysterious
knocking now concluded, and a brick in the chimney began to move.

It came out, and immediately a hand with a rin
