This was curious, for No. 252 was entirely surrounded by houses, its only windows opening on a courtyard into which no eye could look from the hôtels of the Rue M. le Prince and the Rue de l'Ecole, and the mystery was one of the choice possessions of the Latin Quarter.
Once a year the austerity of the place was broken, and the denizens of the whole quarter stood open-mouthed watching many carriages drive up to No. 252, many of them private, not a few with crests on the door panels, from all of them descending veiled female figures and men with coat collars turned up. Then followed curious sounds of music from within, and those whose houses joined the blank walls of No. 252 became for the moment popular, for by placing the ear against the wall strange music could distinctly be heard, and the sound of monotonous chanting voices now and then. By dawn the last guest would have departed, and for another year the hôtel of Mlle. de Tartas was ominously silent.
Eugene declared that he believed it was a celebration of "Walpurgisnacht," and certainly appearances favored such a fancy.
"A queer thing about the whole affair is," he said, "the fact that every one in the street swears that about a month ago, while I was out in Concarneau for a visit, the music and voices were heard again, just as when my revered aunt was in the flesh. The house was perfectly empty, as I tell you, so it is quite possible that the good people were enjoying an hallucination."
I must acknowledge that these stories did not reassure me; in fact, as Thursday came near, I began to regret a little my determination to spend the night in the house. I was too vain to back down, however, and the perfect coolness of the two doctors, who ran down Tuesday to Meudon to make a few arrangements, caused me to swear that I would die of fright before I would flinch. I suppose I believed more or less in ghosts, I am sure now that I am older I believe in them, there are in fact few things I can not believe. Two or three inexplicable things had happened to me, and, although this was before my adventure with Rendel in Pæstum, I had a strong predisposition to believe some things that I could not explain, wherein I was out of sympathy with the age.
Well, to come to the memorable night of the twelfth of June, we had made our preparations, and after depositing a big bag inside the doors of No. 252, went across to the Chien Bleu, where Fargeau and Duchesne turned up promptly, and we sat down to the best dinner Père Garceau could create.
I remember I hardly felt that the conversation was in good taste. It began with various stories of Indian fakirs and Oriental jugglery, matters in which Eugene was curiously well read, swerved to the horrors of the great Sepoy mutiny, and thus to reminiscences of the dissecting-room. By this time we had drunk more or less, and Duchesne launched into a photographic and Zolaesque account of the only time (as he said) when he was possessed of the panic of fear; namely, one night many years ago, when he was locked by accident into the dissecting-room of the Loucine, together with several cadavers of a rather unpleasant nature. I ventured to protest mildly against the choice of subjects, the result being a perfect carnival of horrors, so that when we finally drank our last crème de cacao and started for "la Bouche d'Enfer," my nerves were in a somewhat rocky condition.
It was just ten o'clock when we came into the street. A hot dead wind drifted in great puffs through the city, and ragged masses of vapor swept the purple sky; an unsavory night altogether, one of those nights of hopeless lassitude when one feels, if one is at home, like doing nothing but drink mint juleps and smoke cigarettes.
Eugene opened the creaking door, and tried to light one of the lanterns; but the gusty wind blew out every match, and we finally had to close the outer doors before we could get a light. At last we had all the lanterns going, and I began to look around curiously. We were in a long, vaulted passage, partly carriageway, partly footpath, perfectly bare but for the street refuse which had drifted in with eddying winds. Beyond lay the courtyard, a curious place rendered more curious still by the fitful moonlight and the flashing of four dark lanterns. The place had evidently been once a most noble palace. Opposite rose the oldest portion, a three-story wall of the time of Francis I., with a great wisteria vine covering half. The wings on either side were more modern, seventeenth century, and ugly, while towards the street was nothing but a flat unbroken wall.
The great bare court, littered with bits of paper blown in by the wind, fragments of packing cases, and straw, mysterious with flashing lights and flaunting shadows, while low masses of torn vapor drifted overhead, hiding, then revealing the stars, and all in absolute silence, not even the sounds of the streets entering this prison-like place, was weird and uncanny in the extreme. I must confess that already I began to feel a slight disposition towards the horrors, but with that curious inconsequence which so often happens in the case of those who are deliberately growing scared, I could think of nothing more reassuring than those delicious verses of Lewis Carroll's:—
