In the evening of that day the Caves seem to have exhausted their emotions, and Mr. Cave, who had been out in the afternoon, supped in a gloomy isolation that contrasted pleasantly with the impassioned controversy of the previous days.  For some time matters were very badly strained in the Cave household, but neither crystal nor customer reappeared.

Now, without mincing the matter, we must admit that Mr. Cave was a liar.  He knew perfectly well where the crystal was.  It was in the rooms of Mr. Jacoby Wace, Assistant Demonstrator at St. Catherine’s Hospital, Westbourne Street.  It stood on the sideboard partially covered by a black velvet cloth, and beside a decanter of American whisky.  It is from Mr. Wace, indeed, that the particulars upon which this narrative is based were derived.  Cave had taken off the thing to the hospital hidden in the dog-fish sack, and there had pressed the young investigator to keep it for him.  Mr. Wace was a little dubious at first.  His relationship to Cave was peculiar.  He had a taste for singular characters, and he had more than once invited the old man to smoke and drink in his rooms, and to unfold his rather amusing views of life in general and of his wife in particular.  Mr. Wace had encountered Mrs. Cave, too, on occasions when Mr. Cave was not at home to attend to him.  He knew the constant interference to which Cave was subjected, and having weighed the story judicially, he decided to give the crystal a refuge.  Mr. Cave promised to explain the reasons for his remarkable affection for the crystal more fully on a later occasion, but he spoke distinctly of seeing visions therein.  He called on Mr. Wace the same evening.

He told a complicated story.  The crystal he said had come into his possession with other oddments at the forced sale of another curiosity dealer’s effects, and not knowing what its value might be, he had ticketed it at ten shillings.  It had hung upon his hands at that price for some months, and he was thinking of “reducing the figure,” when he made a singular discovery.

At that time his health was very bad—­and it must be borne in mind that, throughout all this experience, his physical condition was one of ebb—­and he was in considerable distress by reason of the negligence, the positive ill-treatment even, he received from his wife and step-children.  His wife was vain, extravagant, unfeeling, and had a growing taste for private drinking; his step-daughter was mean and over-reaching; and his step-son had conceived a violent dislike for him, and lost no chance of showing it.  The requirements of his business pressed heavily upon him, and Mr. Wace does not think that he was altogether free from occasional intemperance.  He had begun life in a comfortable position, he was a man of fair education, and he suffered, for weeks at a stretch, from melancholia and insomnia.  Afraid to disturb his family, he would slip quietly from his wife’s side, when his thoughts became intolerable, and wander about the house.  And about three o’clock one morning, late in August, chance directed him into the shop.
