"Six!" he shrieked. "Six! and room for two more! Oh, it's a merry life I lead! Flowers and fruit and love-making" (oh, how I cringed at that!), "and now and then a little spice like this! But where is my pretty Lucetta? Surely she was here a moment ago. How could she have vanished, then, so quickly? I do not see her form amid the trees, there is no trace of her presence upon the lawn, and if they search the house from top to bottom and from bottom to top they will find nothing of her--no, not so much as a print of her footstep or the scent of the violets she so often wears tucked into her hair." These last words, uttered in a different voice from the rest, gave the clue to the whole situation. We saw, even while we all bounded forward to the rescue of the devoted maiden, that he was one of those maniacs who have perfect control over themselves and pass for very decent sort of men except in the moment of triumph; and, noting his look of sinister delight, perceived that half his pleasure and almost his sole reward for the horrible crimes he had perpetrated, was in the mystery surrounding his victims and the entire immunity from suspicion which up to this time he had enjoyed. Meantime Mr. Gryce had covered the wretch with his pistol, and his man, who succeeded in reaching the place even sooner than ourselves, hampered as we were by the almost impenetrable hedge behind which we had crouched, tried to lift the grass-covered lid we could faintly discern there. But this was impossible until I, with almost superhuman self-possession, considering the imperative nature of the emergency, found the spring hidden in the well-curb which worked the deadly mechanism. A yell from the writhing creature cowering under the detective's pistol guided me unconsciously in its action, and in another moment we saw the fatal lid tip and disclose what appeared to be the remains of a second well, long ago dried up and abandoned for the other. The rescue of Lucetta followed. As she had fainted in falling she had not suffered much, and soon we had the supreme delight of seeing her eyes unclose. "Ah," she murmured, in a voice whose echo pierced to every heart save that of the guilty wretch now lying handcuffed on the sward, "I thought I saw Albert! He was not dead, and I----" But here Mr. Gryce, with an air at once contrite and yet strangely triumphant, interposed his benevolent face between hers and her weeping sister's and whispered something in her ear which turned her pallid cheek to a glowing scarlet. Rising up, she threw her arms around his neck and let him lift her. As he carried her--where was his rheumatism now?--out of those baleful grounds and away from the reach of the maniac's mingled laughs and cries, her face was peace itself. But his--well, his was a study. XL EXPLANATIONS
