“My dear madam,” said I, “I am an old campaigner, and if I were not I can very well see that no apology is needed. If I can be of any assistance, either to you or to my friend here, I shall be indeed happy.”

Sherlock Holmes seemed to be embarrassed by the question. “Frankly, now!” she repeated, standing upon the rug and looking keenly down at him as he leaned back in a basket-chair.
He snatched it from her in his eagerness, and smoothing it out upon the table he drew over the lamp and examined it intently. I had left my chair and was gazing at it over his shoulder. The envelope was a very coarse one and was stamped with the Gravesend postmark and with the date of that very day, or rather of the day before, for it was considerably after midnight.
