Brainerd lay sleeping near me, and I thought of his comment, 'A conundrum?' Why not search for the answer in these white billets, and, finding it, take the little black bag to the bureau of the 'lost or found'?
I took up the bag, opened it, hesitated, and put it down. Why should I read those letters from a stranger, and to a stranger? I leaned out of the window and drank in the loveliness all about me, illuminated by a faint young moon.
'A conundrum?' I took up the letter post-marked Boston, and slowly drew out--ah, it was more than a mere letter that my hand touched that night. I had put my finger upon a thread in the web of fate!
I am not superstitious, and I certainly had no intimation then of the part these letters would soon play in my World's Fair adventures, nor of the use I should make of them; but I opened that letter with an uncomfortable feeling of curiosity and interest, and without even pausing to look again at the tiny grotesque faces of that little bridge procession so artistically sketched upon the envelope.
The letter, like its cover, was dated from Boston, and was just four days old.
'Just received,' I said to myself, as I took up the wrapper to look at the Chicago postmark. 'Yes, came last night. She must have read it this very morning, sitting upon some one of those shaded seats on Wooded Island, and after reading it she must have amused herself by copying the people passing over the nearest bridge. Ergo, she must have been alone.' My detective instincts were rousing themselves; already I was half unconsciously handling that unread letter as if it were a 'feature' in a 'case.'
She was alone, too, when we met on Midway; that is, I saw no companion. Could it be possible that the young lady was really alone in this densely populated place? How absurd! I looked at the letter again.
It was written in a beautiful flowing hand, and I said, after a moment's scrutiny, 'Written in haste and under excitement.' There were eight closely written pages, and having begun their perusal, I read to the end without a pause. The letter was signed 'Hilda O'Neil,' and there was no street number nor post-office box, only the name of the city from whence it came, Boston.
Hilda O'Neil was the name written on the second letter, this and nothing more; but this no longer surprised me. Miss O'Neil was a New York girl, and a guest, at the time of writing, of the sister of her affianced, in Boston. This young man was already in Chicago, making arrangements for his family, who were to come as soon as informed by him that apartments in the already crowded city were in waiting. They were 'all ready for the flitting,' and were now wondering why 'Gerry' did not wire them. He had written that his plans 'were near completion,' and that he should telegraph them in two or three days at the latest, at the time of writing. The three days were just about to expire, hence the excitement visible in the penmanship of Miss O'Neil. Betwixt impatience and anxiety she confessed herself 'growing really fidgety,' especially as 'Gerry' was always so prompt, 'and then--don't think me silly, dear--but, really, Chicago is such a wicked, dangerous place, especially now.'
