"That, had he met a policeman, he could have explained everything, and referred him to Caprice as to his interview, and right to come out of the house. In a word, it proves he did not steal the diamonds." "Then who, in Heaven's name, did?" "I don't give an opinion unless I'm certain," said Naball deliberately; "but I'll tell you what I think. You heard Caprice say she won't go on with the case? "Yes; I can't understand her reason." "I can; she stole the diamonds herself." CHAPTER IX. AN UNKNOWN BENEFACTOR. Everyone was greatly excited over the great jewel robbery, especially as it had taken place at the house of so celebrated a person as Caprice, and numerous were the conjectures as to the discovery of the thieves. When, however, it became known that the lady in question declined to allow an investigation to be made, and was apparently contented to lose five thousand pounds' worth of diamonds, the excitement grew intense. What was her motive for acting in such a strange way? All Melbourne asked itself this question, but without obtaining a satisfactory answer. Reference was made to Kitty's antecedents in connection with the Midas poisoning case, and the public were quite prepared to hear any evil of her, particularly as her career since then had been anything but pure. The name of Villiers was mentioned, and then it transpired that Villiers had been seen outside her house on the night of the robbery It was curious that another crime should have happened where these two, formerly implicated in a murder case, should have come together, and disagreeable rumours began to circulate. Then, by some unexplained means, the opinion of Naball became known regarding his assertion that Caprice had stolen the diamonds herself. Here was another mystery. Why on earth should she steal her own jewels? One theory was that she required money, and had sold them for this purpose, pretending that they were stolen, in order to satisfy the lovers who gave them to her. This was clearly absurd, as Caprice cared nothing for the opinion of her lovers, and, moreover, the donors of the diamonds were long since dead or ruined, so the idea of the detective was unanimously laughed at. But then the fact remained, she would not allow an investigation to be made; and how was this to be accounted for? One idea was mooted, that Villiers had stolen the diamonds, and she would not prosecute him because he was the husband of the woman who had been kind to her. In this case, however, she would have easily got back her jewels by a threat of prosecution, whereas they were still missing. Other solutions of the problem were offered, but they were unsatisfactory, and Melbourne settled itself down to the opinion that the whole affair was a mystery which would never be solved.
