“I’d very much like to ‘conclude' something from this experiment. Or that it should raise a question in my mind, and a commitment to get to the bottom of the matter, to investigate, to come up with an outline of the beginning of an answer, however ill-defined or trite it might be . . . But no. I’m here to see, hear, observe - to experience. Let others explain.”

“In response to a tactless question he once said to me, ‘What do you expect? This lousy neighbourhood gave me the come-on. I couldn’t resist.”

“Sunset’s the best time to take a stroll down Mouffetard, the ancient Via Mons Cetardus. The buildings along it are only two or three stories high. Many are crowned with conical dovecotes. Nowhere in Paris is the connection, the obscure kinship, between houses very close to each other more perceptible to the pedestrian than in this street.Close in age, not location. If one of them should show signs of decrepitude, if its face should sag, or it should lose a tooth, as it were, a bit of cornicing, within hours its sibling a hundred metres away, but designed according to the same plans and built by the same men, will also feel it’s on its last legs.The houses vibrate in sympathy like the chords of a viola d’amore. Like cheddite charges giving each other the signal to explode simultaneously.”

“Here, in a few words, you’ve said all you need to say. People stand by each other, but they don’t talk. It’s remarkable. I’ve investigated the extraordinary history of these walls. I think I’m the only person who knows that it’s the stones, the stones alone that set the tone here.”

“Old Hubert must have had a premonition of his squalid demise. In October he said to me, ‘Forty-two years I’ve had this place. I’d really like to go back home, but I ain’t got the energy since my old girl died. And I can’t sell it the way it is now. But anyway before I hang my hat up I’d be curious to know what’s in that third cellar of mine.’The third cellar has been walled up by order of the civil defence authorities after the floods of 1910. A double barrier of cemented bricks prevents the rising waters from invading the upper floors when flooding occurs. In the event of storms or blocked drains, the cellar acts as a regulatory overflow.The weather was fine: no risk of drowning or any sudden emergency. There were five of us: Hubert, Gerard the painter, two regulars and myself. Old Marteau, the local builder, was upstairs with his gear, ready to repair the damage. We made a hole.Our exploration took us sixty metres down a laboriously-faced vaulted corridor (it must have been an old thoroughfare). We were wading through a disgusting sludge. At the farend, an impassable barrier of iron bars. The corridor continued beyond it, plunging downwards. In short, it was a kind of drain-trap.That’s all. Nothing else. Disappointed, we retraced our steps. Old Hubert scanned the walls with his electric torch. Look! An opening. No, an alcove, with some wooden object that looks like a black statuette. I pick the thing up: it’s easily removable. I stick it under my arm. I told Hubert, ‘It’s of no interest. . .’ and kept this treasure for myself.I gazed at it for hours on end, in private. So my deductions, my hunches were not mistaken: the Bièvre-Seine confluence was once the site where sorcerers and satanists must surely have gathered. And this kind of primitive magic, which the blacks of Central Africa practise today, was known here several centuries ago. The statuette had miraculously survived the onslaught of time: the well-known virtues of the waters of the Bièvre, so rich in tannin, had protected the wood from rotting, actually hardened, almost fossilized it. The object answered a purpose that was anything but aesthetic. Crudely carved, probably from heart of oak. The legs were slightly set apart, the arms detached from the body. No indication of gender. Four nails set in a triangle were planted in its chest. Two of them, corroded with rust, broke off at the wood’s surface all on their own. There was a spike sunk in each eye. The skull, like a salt cellar, had twenty-four holes in which little tufts of brown hair had been planted, fixed in place with wax, of which there were still some vestiges. I’ve kept quiet about my find. I’m biding my time.”

“Fortunately the City is vigilant. It too has its secret weapons. Since the summer it has released safety valves that form part of a wonderful mechanism, known only to itself. For the past three months we’ve noticed the most heartening appearance all over the place of eccentrics, more or less raving lunatics, cranks, and reinvigorating crackpots.”

“I should like one day, as some anonymous pedestrian revisiting the scenes of these memories, to follow on the heels of an attentive reader - here are some - and to relish his delight when, with this book in his pocket, he finds himself in the presence of one of the characters described, mentioned or referred to earlier on, who do exist, large as life, and wittingly or not perpetuate their legend. I’d like people to investigate, to verify. You need to be an extremely well-informed reader to identify all the ‘keys’ scattered throughout these pages. Many readers may find among them the key to their own front door.In any case, what you need to know is this: in certain areas of Paris, the supernatural is part of everyday life. Local people accept this and have some involvement with it.”

“Better beware of the newly deadOf the white-handed ghostAnd the brightness of these lamps . . .wrote Luc Berimont in 1940, in Reign of Darkness.I’ve always felt the greatest reluctance to go anywhere near, to touch, a fresh corpse. For me, it’s an unseemly thing. Useless. Hostile. Cunning. Dangerous. The ‘presence’ is much stronger, more perceptible one hour after death than one hour before. By my observation, this was not the case with Heisserer.He was entirely absent from his head, his hands,his quivering body. He was gone instantly, unburdened of his absurd life, released.”

“An event is never just what it is in itself and nothing more. It’s what goes on around it, at the same time, that makes it — potentially — a tragic situation.You have to have been exposed to this, at least once, to understand it.”

“I’d very much like to ‘conclude' something from this experiment. Or that it should raise a question in my mind, and a commitment to get to the bottom of the matter, to investigate, to come up with an outline of the beginning of an answer, however ill-defined or trite it might be . . . But no. I’m here to see, hear, observe - to experience. Let others explain.”

“Silence, like madness, is only comparative.”
