Roland pointed it out. “That was it, sir.”

“That!” Mr. Galloway bent on it a keener glance, which probably satisfied him that it bore his private address. “Was this the only one he brought?” added he; and from his manner and words Roland inferred that it was not the letter he had expected.

“That was all, sir.”

Roland returned to his own room, and Mr. Galloway sat down and opened his letters. The first two were short communications relative to business; the last was the one brought by John.

What did it contain? For one thing, It contained a bank-note for twenty pounds. But the contents? Mr. Galloway gazed at it and rubbed his brow, and gazed again. He took off his spectacles, and put them on; he looked at the bank-note, and he read and re-read the letter; for it completely upset the theory and set at nought the data he had been going upon; especially the data of the last few hours.

“The finder of that lost twenty-pound note sends it back to Mr. Galloway. His motive in doing so is that the wrongly suspected may be cleared. He who was publicly accused of the offence was innocent, as were all others upon whom suspicion (though not acted upon) may have fallen. The writer of this alone took the note, and now restores it.”

Abrupt and signatureless, such was the letter. When Mr. Galloway had sufficiently overcome his surprise to reason rationally, it struck him as being a singular coincidence that this should come to him on the day when the old affair had been renewed again. Since its bustle had died out at the time of the occurrence, Mr. Galloway did not remember to have voluntarily spoken of it, until that morning with Roland Yorke.

He took up the bank-note. Was it the one actually taken—the same note—kept possibly, in fear, and now returned? He had no means of knowing. He thought it was not the same. His recollection of the lost note had seemed to be that it was a dirty note, which must have passed through many hands; but he had never been quite clear upon that point. This note was clean and crisp. Who had taken it? Who had sent it back? It quite disposed of that disagreeable suspicion touching his cousin. Had his cousin so far forgotten himself as to take the note, he would not have been likely to return it: he knew nothing of the proceedings which had taken place in Helstonleigh, for Mr. Galloway had never mentioned them to him. The writer of this letter was cognizant of them, and had sent it that they might be removed.

At the first glance, it of course appeared to be proof positive that Arthur Channing was not guilty. But Mr. Galloway was not accustomed to take only the superficial view of things: and it struck him, as it would strike others, that this might be, after all, a refined bit of finessing on Arthur’s own part to remove suspicion from himself. True, the cost of doing so was twenty pounds: but what was that compared with the restoration of his good name?

The letter bore the London post-mark. There was not a doubt that it had been there posted. That betrayed nothing. Arthur, or any one else, could have a letter posted there, if wishing to do it. “Where there’s a will, there’s a way,” thought Mr. Galloway. But again, where was Arthur Channing to procure twenty pounds from? Mr. Galloway did not think that he could procure this sum from anywhere, or that he possessed, himself, a twentieth part of it. So far the probability was against Arthur’s being the author. Mr. Galloway quite lost himself in conjectures. Why should it have been addressed to his residence, and not to the office? He had been expecting a letter from one, that afternoon, who always did address to his residence: and that letter, it appeared, had not arrived. However, that had nothing to do with this. Neither paper nor writing afforded any clue to the sender, and the latter was palpably disguised.
