One woe doth tread upon another’s heel,

So fast they follow.

Hamlet.

Later, I asked myself many questions, and wandered into mazes of speculation which only puzzled me and led nowhere. I remembered the bottles; I remembered the ring. I went back, in fancy, to the hour of my own entrance into the club-house, and, recalling each circumstance, endeavoured to fit the facts of Arthur’s story with those of my own experience.

Was he in the building when I first stepped into it? It was just possible. I had been led to prevaricate as to the moment I entered the lower gateway, and he may have done the same as to the hour he left by the upper hall window. Whatever his denials on this or any subject, I was convinced that he knew, as well as I, that Carmel had been in the building with her sister, and was involved more or less personally in the crime committed there. Might it not be simply as his accessory after the fact? If only I could believe this! If my knowledge of him and of her would allow me to hug this forlorn hope, and behold, in this shock to her brain, and in her look and attitude on leaving the club-house, only a sister’s horror at a wilful brother’s crime!

But one fact stood in the way of this — a fact which nothing but some predetermined, underhanded purpose on her part could explain. She had gone in disguise to The Whispering Pines, and she had returned home in the same suspicious fashion. The wearing of her brother’s hat and coat over her own womanly garments was no freak. There had been purpose in it — a purpose which demanded secrecy. That Adelaide should have accompanied her under these circumstances was a mystery. But then the whole affair was a mystery, totally out of keeping, in all its details, with the characters of these women, save — and what a fearful exception I here make — the awful end, which, alas! bespoke the fiery rush and impulse to destroy which marked Carmel’s unbridled rages.

Of a less emotional attack she would be as incapable as any other good woman. Poison she would never use. Its presence there was due to another’s forethought, another’s determination. But the poison had not killed. Both glasses had been emptied, but — Ah! those glasses. What explanation had the police, now, for those two emptied glasses? They had hitherto supposed me to be the second person who had joined Adelaide in this totally uncharacteristic drinking.

To whom did they now attribute this act? To Arthur, the brother whose love for liquor in every form she had always decried, and had publicly rebuked only a few hours before? Knowing nothing of Carmel having been on the scene, they must ascribe this act either to him or to me; and when they came to dwell upon this point more particularly — when they came to study the exact character of the relations which had always subsisted between Adelaide and her brother — they must see the improbability of her drinking with him under any circumstances. Then their thoughts would recur to me, and I should find myself again a suspect. The monstrous suggestion that Arthur had brought the liquor there himself, had poured it out and forced her to drink it, poison and all, out of revenge for her action at the dinner-table a short time before, did not occur to me then, but if it had, there were the three glasses — he would not bring three; nor would Adelaide; nor, as I saw it, would Carmel.

Chaos! However one looked at it, chaos! Only one fact was clear — that Carmel knew the whole story and might communicate the same, if ever her brain cleared and she could be brought to reveal the mysteries of t............
