However, the Englishman (let us call him Dennistoun) was soon too deep in his note-book and too busy with his camera to give more than an occasional glance to the sacristan. Whenever he did look at him, he found him at no great distance, either huddling himself back against the wall or crouching in one of the gorgeous stalls. Dennistoun became rather fidgety after a time. Mingled suspicions that he was keeping the old man from his déjeuner, that he was regarded as likely to make away with St Bertrand’s ivory crozier, or with the dusty stuffed crocodile that hangs over the font, began to torment him.

“Won’t you go home?” he said at last; “I’m quite well able to finish my notes alone; you can lock me in if you like. I shall want at least two hours more here, and it must be cold for you, isn’t it?”

“Good heavens!” said the little man, whom the suggestion seemed to throw into a state of unaccountable terror, “such a thing cannot be thought of for a moment. Leave monsieur alone in the church? No, no; two hours, three hours, all will be the same to me. I have breakfasted, I am not at all cold, with many thanks to monsieur.”

“Very well, my little man,” quoth Dennistoun to himself: “you have been warned, and you must take the consequences.”

Before the expiration of the two hours, the stalls, the enormous dilapidated organ, the choir-screen of Bishop John de Mauléon, the remnants of glass and tapestry, and the objects in the treasure-chamber, had been well and truly examined; the sacristan still keeping at Dennistoun’s heels, and every now and then whipping round as if he had been stung, when one or other of the strange noises that trouble a large empty building fell on his ear. Curious noises they were sometimes.

“Once,” Dennistoun said to me, “I could have sworn I heard a thin metallic voice laughing high up in the tower. I darted an inquiring glance at my sacristan. He was white to the lips. ‘It is he—that is—it is no one; the door is locked,’ was all he said, and we looked at each other for a full minute.”

Another little incident puzzled Dennistoun a good deal. He was examining a large dark picture that hangs behind the altar, one of a series illustrating the miracles of St Bertrand. The composition of the picture is well-nigh indecipherable, but there is a Latin legend below, which runs thus:

Qualiter S. Bertrandus liberavit hominem quem diabolus diu volebat strangulare. (How St Bertrand delivered a man whom the Devil long sought to strangle.)

Dennistoun was turning to the sacristan with a smile and a jocular remark of some sort on his lips, but he was confounded to see the old man on his knees, gazing at the picture with the eye of a suppliant in agony, his hands tightly clasped, and a rain of tears on his cheeks. Dennistoun naturally pretended to have noticed nothing, but the question would not go away from him, “Why should a daub of this kind affect anyone so strongly?” He seemed to himself to be getting some sort of clue to the reason of the strange look that had been puzzling him all the day: the man must be a monomaniac; but what was his monomania?

It was nearly five o’clock; the short day was drawing in, and the church began to fill with shadows, while the curious noises—the muffled footfalls and distant talking voices that had been perceptible all day—seemed, no doubt because of the fading light and the consequently quickened sense of hearing, to become more frequent and insistent.
