"Most emphatically I do. Otherwise, why should Rent go to the trouble of all these elaborate preparations? He was afraid that Hortense would betray him to her mistress. He was so infatuated with Mrs. Charlock that he was prepared to run any risk to retain her good opinion. I feel convinced that Hortense was sent deliberately to her death, and if you and I had not happened to be in the neighbourhood the thing would have been forgotten and nobody been any the wiser. Why, apart from such proofs as I have given you just now, there are other people who could support my assertions. Don't you suppose that that blackguard Bark knows all about it? And he was prepared to keep his mouth shut and leave his sister's death unpunished if only he could get possession of the jewels. It is a ghastly business altogether. And now you understand why I am not anxious to face Mrs. Rent. And you will see that the matter cannot be allowed to rest here. What a sensation there will be when it all comes out!"
CHAPTER XLVII
ABSOLUTION
Tanza shook his head slowly and sorrowfully. "Terrible!" he murmured. "I wish we could find some way of keeping Mrs. Rent and Miss Hargrave out of this matter. But after what has taken place the thing is impossible. Mrs. Rent will have to give evidence, and so will Miss Hargrave. One is naturally loth to interfere with the course of justice. But if ever there was a case where a policy of silence would be pardonable, this assuredly is that case. Only in one contingency the world need know nothing of this miserable affair."
"And what may that be?" Grey asked.
"Why, the death of Arnold Rent, of course. If he would considerately die, we should be perfectly justified in keeping our own counsel. Why should the thing be dragged to light? Why should the whole painful story be made public when the culprit is beyond the reach of the law? I think you will agree with me."
"Oh, I do," Grey confessed. "But please don't imagine that Arnold is worse than he appears to be. You don't suppose that he is responsible for the death of Mrs. Charlock as well? That would be too dreadful."
"Is there any other conclusion?" Tanza asked.
"Well, yes, in common justice to Rent, there is. I believe that Mrs. Charlock's death was a sheer accident. Let me retrace the ground, and I will show you what I mean. We will admit, if you like, that Rent is a man without heart and without principle. We will make one exception, and that was his pure and disinterested affection for Mrs. Charlock. He was prepared to sacrifice his future for her sake. Oh, yes, I know that he stole her diamonds. But no doubt that was in the early stage of his infatuation. Afterwards he must be credited with good intentions. You see, he had removed the French maid, and the ground appeared to be clear. So deeply in love is he that he takes Mrs. Charlock to stay with his mother. Mind you, in taking that step he knew what he was risking. He knew how strict and rigid his mother was, and how little versed she was in the ways of the world. These upright and honourable people are apt to be narrow-minded. And religion and charity are not always the same thing. I say that when Rent took Mrs. Charlock into Devonshire he was running the risk of losing every penny of his expectations. Of course, there was the hope of conciliating his mother, but that was what one might call a sporting chance. As you know, the scheme was a failure, and Mrs. Charlock went away, posing as a martyr, prepared to accept any sacrifice rather than injure the prospects of the man who had befriended her. Anyway, there was an end of her so far as the home in Devonshire was concerned. Now, if my theory is correct, there was a subsequent interview between Mrs. Charlock and Rent, in which the situation was reviewed from a worldly point of view. You see, they were bound to face the situation sooner or later; in sporting parlance, the thing wasn't good enough for Mrs. Charlock, and she probably let Rent know it in her sweet, unsophisticated way. No doubt he had time to think the matter over and began to grasp what he was sacrificing. Whether they parted in friendly fashion or not doesn't matter. They did part, and Mrs. Charlock came back to her husband. Before she started, Rent doubtless did the fair thing and told her where her jewels were hidden. But there was one thing he forgot—he neglected to turn off those switches, and left the fountain in the same dangerous condition as when Hortense met with her dreadful death. Either that or Swift had been experimenting with the apparatus. But the fact remains that the charge had not been drawn from the mine, and when Mrs. Charlock went to regain possession of her jewels she went to certain death. That is my rendering of the matter, though I may be wrong."
"I should think it exceedingly probable you are right," Tanza said. "You have given me a sensible and logical account of what has happened, and I fail to see any flaw in your argument. We had better return to the yacht now, and later I will hand these stones to Charlock. There ought to be enough here to free him from all his difficulties and enable him to come back to his own house. Unless I am mistaken, he will be glad to resume possession once more."
