I saw it all now. That terrible light in his eyes was the light of insanity. That stony look in his face was the fixed, hopeless melancholy of a mind diseased.

"Does he know that he is mad?" I asked, as the landlord rose to go.

He shrugged his shoulders and looked doubtful.

"I have not said that the Père Chessez is mad, mein Herr," he replied. "He has strange fancies sometimes, and takes his fancies for facts—that is all. But I am quite sure that he does not believe himself to be less sane than his neighbours."

So the innkeeper left me, and I (my head full of the story I had just heard) put on my hat, went out into the market-place, asked my way to the Basel Thor, and set off to explore the scene of the Frau Margaret's murder.

I found it without difficulty—a long, low-fronted, beetle-browed farmhouse, lying back a meadow's length from the road. There were children playing upon the threshold, a flock of turkeys gobbling about the barn-door, and a big dog sleeping outside his kennel close by. The chimneys, too, were smoking merrily. Seeing these signs of life and cheerfulness, I abandoned all idea of asking to go over the house. I felt that I had no right to carry my morbid curiosity into this peaceful home; so I turned away, and retraced my steps towards Rheinfelden.

It was not yet seven, and the sun had still an hour's course to run. I re-entered the town, strolled back through the street, and presently came again to the Friedrich's Thor and the path leading to the church. An irresistible impulse seemed to drag me back to the place.

The doors were closed; a goat was browsing among the graves; and the rushing of the Rhine, some three hundred yards away, was distinctly audible in the silence. I looked round for the priest's house—the scene of the first murder; but from this side, at all events, no house was visible. Going round, however, to the back of the church, I saw a gate, a box-bordered path, and, peeping through some trees, a chimney and the roof of a little brown-tiled house.

This, then, was the path along which Caspar Rufenacht, with the priest's blood upon his hands and the priest's gown upon his shoulders, had taken his guilty way to the confessional! How quiet it all looked in the golden evening light! How like the church-path of an English parsonage!

I wished I could have seen something more of the house than that bit of roof and that one chimney. There must, I told myself, be some other entrance—some way round by the road! Musing and lingering thus, I was startled by a quiet voice close against my shoulder, saying:—
