Mlle. Blaye lived, it seems, all alone, except for one female servant of her own age; a severe, taciturn creature, with massive Breton features and a Breton tongue, whenever she vouchsafed to use it. No one ever was seen to enter the door of No. 252 except Jeanne the servant and the Sar Torrevieja, the latter coming constantly from none knew whither, and always entering, _never leaving_. Indeed, the neighbors, who for eleven years had watched the old sorcerer sidle crab-wise up to the bell almost every day, declared vociferously that _never_ had he been seen to leave the house. Once, when they decided to keep absolute guard, the watcher, none other than Maître Garceau of the Chien Bleu, after keeping his eyes fixed on the door from ten o'clock one morning when the Sar arrived until four in the afternoon, during which time the door was unopened (he knew this, for had he not gummed a ten-centime stamp over the joint and was not the stamp unbroken) nearly fell down when the sinister figure of Torrevieja slid wickedly by him with a dry "Pardon, Monsieur!" and disappeared again through the black doorway. 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."
