Mr. Cave had living with him a step-daughter and a step-son, and at supper that night the transaction was re-discussed. None of them had a high opinion of Mr. Cave's business methods, and this action seemed a culminating folly. "It's my opinion he's refused that crystal before," said the step-son, a loose-limbed lout of eighteen. "But _Five Pounds_!" said the step-daughter, an argumentative young woman of six-and-twenty. Mr. Cave's answers were wretched; he could only mumble weak assertions that he knew his own business best. They drove him from his half-eaten supper into the shop, to close it for the night, his ears aflame and tears of vexation behind his spectacles. Why had he left the crystal in the window so long? The folly of it! That was the trouble closest in his mind. For a time he could see no way of evading sale. After supper his step-daughter and step-son smartened themselves up and went out and his wife retired upstairs to reflect upon the business aspects of the crystal, over a little sugar and lemon and so forth in hot water. Mr. Cave went into the shop, and stayed there until late, ostensibly to make ornamental rockeries for gold-fish cases, but really for a private purpose that will be better explained later. The next day Mrs. Cave found that the crystal had been removed from the window, and was lying behind some second-hand books on angling. She replaced it in a conspicuous position. But she did not argue further about it, as a nervous headache disinclined her from debate. Mr. Cave was always disinclined. The day passed disagreeably. Mr. Cave was, if anything, more absent-minded than usual, and uncommonly irritable withal. In the afternoon, when his wife was taking her customary sleep, he removed the crystal from the window again. The next day Mr. Cave had to deliver a consignment of dog-fish at one of the hospital schools, where they were needed for dissection. In his absence Mrs. Cave's mind reverted to the topic of the crystal, and the methods of expenditure suitable to a windfall of five pounds. She had already devised some very agreeable expedients, among others a dress of green silk for herself and a trip to Richmond, when a jangling of the front door bell summoned her into the shop. The customer was an examination coach who came to complain of the non-delivery of certain frogs asked for the previous day. Mrs. Cave did not approve of this particular branch of Mr. Cave's business, and the gentleman, who had called in a somewhat aggressive mood, retired after a brief exchange of words--entirely civil, so far as he was concerned. Mrs. Cave's eye then naturally turned to the window; for the sight of the crystal was an assurance of the five pounds and of her dreams. What was her surprise to find it gone! She went to the place behind the locker on the counter, where she had discovered it the day before. It was not there; and she immediately began an eager search about the shop.
