mind engaged upon some agitating theme. The man was seen watching the window inside which Marie Prévol and her admirer were seated. He moved away when he saw himself observed. He had disguised himself as much as he could by turning up the collar of his coat; and who can doubt that this was the same man who had been seen by Léonie in the railway-station, watching Marie Prévol and her lover from behind the door of the waiting-room? The dark spectacles were part of a disguise. These are all details that point to one conclusion. The finding of the hat induced me to visit every shop in Saint-Germain where a hat could be bought. It was clear that the murderer could not have gone far from the forest bare-headed, without attracting attention. He must have procured a hat somehow; and it was not long before I ascertained that a hat had been bought late on that very evening. At a shop in an out-of-the-way corner of the town I was told that a boy, a gamin, had come in on the night of the murder, and had asked for a cloth travelling-cap. He had chosen one with flaps to protect the ears, a form of cap intended to give the utmost protection from cold. He paid for his purchase with a napoleon, and seemed in a great hurry to be gone, not even stopping to count his change. The shopkeeper had wondered at such a little ragamuffin being intrusted with a purchase of the kind.

I went from the hatter's to the railway-station, and there, after having been bandied about from pillar to post, I succeeded in finding a tolerably intelligent official who remembered the night of the murder—now ten days past—and who could recall most of the passengers who had left for Paris by the half-past nine o'clock train upon that particular night. The news of the murder had not been brought to the station before the starting of the train: a most criminal neglect on the part of the local police. No suspicious-looking person had been observed to enter the train; but upon my questioning him closely, the man remembered having noticed a traveller who wore a cloth cap with flaps over the ears—a seemingly needless protection upon a mild September evening. 'There is one who takes care of himself,' the railway official had thought. For the rest, this passenger had looked like a gentleman, tall, erect, well-built, a bigger man than the majority of Frenchmen—what the railway official permitted himself to call un bel homme. Had he appeared agitated, breathless,
