Ishmael opened the letter and read as follows:

"Castle Cragg, near Banff, Buchan, Scotland. "My Dearest Father: We are all in good health; therefore do not be alarmed, even though I earnestly implore you to drop everything you may have in hand and come over to me immediately, by the very first steamer that sails after your receipt of this letter. Father, you will comply with my entreaty when I inform you that I have been deceived and betrayed by him who swore to cherish and protect me. My life and honor are both imperiled. I will undertake to guard both for a month, until you come. But come at once to your wronged but "Loving child, "Claudia."

"Good Heaven, sir, what does this mean?" exclaimed Ishmael, looking up, after he had read the letter.

"I do not clearly know myself. It is what I wish you to help me to find out."

"But—when was this letter received?"

"On Monday last."

"On Monday last," repeated Ishmael, glancing at the envelope; "that was the 5th of December; and it is postmarked 'Banff, October 15th.' Is it possible that this important letter has been seven weeks on its way?"

"Yes, it is quite possible. If yea look at the envelope closely you will see that it is stamped 'Missent,' and remailed from San Francisco, California, to which place it was sent by mistake. You perceive it has traveled half around the world before coming here."

"How very unfortunate! and a letter so urgent as this! Sir, can you give me any idea of the danger that threatens Lady Vincent?" inquired Ishmael, raising his eyes for a moment from his study of the letter.

"Read this second letter; I received it, and a third one, by the very same mail that brought the long-delayed first one," replied the judge.
