I fancy that it had been there long before the avenue was constructed, for the grey tiles were stained with lichens, and the walls were mildewed and discoloured with age. It looked a small house from the street, five windows in front, if I remember right, but it deepened into a single long chamber at the back. It was here that Dacre had that singular library of occult literature, and the fantastic curiosities which served as a hobby for himself, and an amusement for his friends. A wealthy man of refined and eccentric tastes, he had spent much of his life and fortune in gathering together what was said to be a unique private collection of Talmudic, cabalistic, and magical works, many of them of great rarity and value. His tastes leaned toward the marvellous and the monstrous, and I have heard that his experiments in the direction of the unknown have passed all the bounds of civilization and of decorum. To his English friends he never alluded to such matters, and took the tone of the student and virtuoso; but a Frenchman whose tastes were of the same nature has assured me that the worst excesses of the black mass have been perpetrated in that large and lofty hall, which is lined with the shelves of his books, and the cases of his museum.
Dacre's appearance was enough to show that his deep interest in these psychic matters was intellectual rather than spiritual. There was no trace of asceticism upon his heavy face, but there was much mental force in his huge, dome-like skull, which curved upward from amongst his thinning locks, like a snowpeak above its fringe of fir trees. His knowledge was greater than his wisdom, and his powers were far superior to his character. The small bright eyes, buried deeply in his fleshy face, twinkled with intelligence and an unabated curiosity of life, but they were the eyes of a sensualist and an egotist. Enough of the man, for he is dead now, poor devil, dead at the very time that he had made sure that he had at last discovered the elixir of life. It is not with his complex character that I have to deal, but with the very strange and inexplicable incident which had its rise in my visit to him in the early spring of the year '82.
I had known Dacre in England, for my researches in the Assyrian Room of the British Museum had been conducted at the time when he was endeavouring to establish a mystic and esoteric meaning in the Babylonian tablets, and this community of interests had brought us together. Chance remarks had led to daily conversation, and that to something verging upon friendship. I had promised him that on my next visit to Paris I would call upon him. At the time when I was able to fulfil my compact I was living in a cottage at Fontainebleau, and as the evening trains were inconvenient, he asked me to spend the night in his house.
"I have only that one spare couch," said he, pointing to a broad sofa in his large salon; "I hope that you will manage to be comfortable there."
It was a singular bedroom, with its high walls of brown volumes, but there could be no more agreeable furniture to a bookworm like myself, and there is no scent so pleasant to my nostrils as that faint, subtle reek which comes from an ancient book. I assured him that I could desire no more charming chamber, and no more congenial surroundings.
"If the fittings are neither convenient nor conventional, they are at least costly," said he, looking round at his shelves. "I have expended nearly a quarter of a million of money upon these objects which surround you. Books, weapons, gems, carvings, tapestries, images--there is hardly a thing here which has not its history, and it is generally one worth telling."
He was seated as he spoke at one side of the open fire-place, and I at the other. His reading-table was on his right, and the strong lamp above it ringed it with a very vivid circle of golden light. A half-rolled palimpsest lay in the centre, and around it were many quaint articles of bric-a-brac. One of these was a large funnel, such as is used for filling wine casks.
