As these thoughts ran through my mind, I was finishing my Pêche Cécilie (I spurn all sweets ordinarily), when I became interested in the unusual conduct of a young woman who had entered the front door briskly and walked with a business-like air to the cashier's desk. The girl within the wicket rose promptly, opened the screen, and without parley of any sort, emptied the contents of her till into the visitor's reticule. With a nod and a smile and a moment's careless survey of the room, the girl departed, swinging the reticule in her hand. A long roll she carried under her arm confirmed my identification. It was Miss Octavia Hollister's Swedish maid; and the roll, beyond peradventure, contained the plans she had obtained at Pepperton's office.

The girl was well-featured, neat of figure, and becomingly gowned, and as I watched her leave the shop the lightness of her step, something smooth and flowing in her movements, interested me. I did not know what business she had to be robbing the Asolando money-drawer, but it was altogether possible that she was the Hopefield ghost!

On the whole, when I had finally torn myself away from my assistant,—who made no attempt to conceal his doubts as to my sanity,—and had settled myself in the four-fourteen express with the afternoon papers, I was fully satisfied with the day's adventures.

THE RIDDLE OF THE SIBYL'S LEAVES

I had told the coachman in the morning not to trouble to meet me on my return, and I engaged the village liveryman to drive me to the house for hire. As we approached Hopefield I saw the Napoleonic figure of John Stewart Dick in the roadway. He had evidently been waiting for me. He held up his hand with the superb, impersonal scorn of a Fifth Avenue policeman, and the driver checked his horse.

"I gave you warning," he said impressively. "If you return to the house the consequences will be upon your own head."

"Thank you," I replied courteously. "You lay yourself open to the severest penalties of the law in attempting to intimidate me. I have enlisted for the whole campaign. Sick chimneys require my immediate professional attention. If my bark sink, 't is to another sea. Be good, dear child, let those who will be clever; and kindly omit flowers."

As the driver slapped his reins, Dick sprang out of the way, muttering words that proved the shallowness of his philosophic temper. The liveryman expressed his disapproval of the pragmatist in profane terms as we entered the grounds.
