"I have no doubt of it. That spasmodic walk, that hesitancy, the looking back, and then hurrying on--all these indicated a 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. The man had been on the point of closing his shop, and therefore was quite positive as to the hour. It was his invariable habit to put up his shutters at nine o'clock, and the clock was striking as the boy came to the door of the shop, breathless and heated, as if he had been running for some distance." "And you conclude that this travelling-cap was bought for the murderer?"
