Chapter 15

Those who had seen Edgar Caswall familiarly since his arrival, and had already estimated his cold-blooded nature at something of its true value, were surprised that he took so to heart the death of old Chester. The fact was that not one of them had guessed correctly at his character. They thought, naturally enough, that the concern which he felt was that of a master for a faithful old servant of his family. They little thought that it was merely the selfish expression of his disappointment, that he had thus lost the only remaining clue to an interesting piece of family history--one which was now and would be for ever wrapped in mystery. Caswall knew enough about the life of his ancestor in Paris to wish to know more fully and more thoroughly all that had been. The period covered by that ancestor's life in Paris was one inviting every form of curiosity.

Lady Arabella, who had her own game to play, saw in the METIER of sympathetic friend, a series of meetings with the man she wanted to secure. She made the first use of the opportunity the day after old Chester's death; indeed, as soon as the news had filtered in through the back door of Diana's Grove. At that meeting, she played her part so well that even Caswall's cold nature was impressed.

Oolanga was the only one who did not credit her with at least some sense of fine feeling in the matter. In emotional, as in other matters, Oolanga was distinctly a utilitarian, and as he could not understand anyone feeling grief except for his own suffering, pain, or for the loss of money, he could not understand anyone simulating such an emotion except for show intended to deceive. He thought that she had come to Castra Regis again for the opportunity of stealing something, and was determined that on this occasion the chance of pressing his advantage over her should not pass. He felt, therefore, that the occasion was one for extra carefulness in the watching of all that went on. Ever since he had come to the conclusion that Lady Arabella was trying to steal the treasure- chest, he suspected nearly everyone of the same design, and made it a point to watch all suspicious persons and places. As Adam was engaged on his own researches regarding Lady Arabella, it was only natural that there should be some crossing of each other's tracks. This is what did actually happen.

Adam had gone for an early morning survey of the place in which he was interested, taking with him the mongoose in its box. He arrived at the gate of Diana's Grove just as Lady Arabella was preparing to set out for Castra Regis on what she considered her mission of comfort. Seeing Adam from her window going through the shadows of the trees round the gate, she thought that he must be engaged on some purpose similar to her own. So, quickly making her toilet, she quietly left the house, and, taking advantage of every shadow and substance which could hide her, followed him on his walk.

Oolanga, the
