At the door of my apartment I found poor Fido extended, stiff and motionless. Startled by somewhat unnatural in his posture, I called to him. The poor animal looked at me, but did not stir. 'Fido!' I called again, stooping to pat his head. He looked up once more; wagged his tail; gave a short low whine; and died. Many would smile were I to describe what I felt at that moment; and yet I believe there are none who could unmoved lose the last memorial of friend and parent, or part unmoved with the creature which had sported with their infancy, and grown old beneath their care. Fido was my last earthly possession. Besides him I had nothing. I thank Heaven that the greater part of my kind must look back to the deprivations of early childhood, ere they can know what a melancholy value this single circumstance gives to what is in itself of little worth. My feelings took a new turn, when it suddenly occurred to me that my poor old favourite owed his death not to disease, but to poison. His appearance, as well as the suddenness of his death, confirmed the suspicion. Strong indignation already working in my breast, I hastened to question the servants. They all denied the deed; but with such reservations, as showed me that they at least guessed at the perpetrator. Breathless with resentment, and with a vain desire to vent it all, yet to vent it calmly, I entered Mrs Boswell's apartment, and steadily questioned her upon the fact. Mrs Boswell forgot her late alarm, or rather my flashing eye was for a moment an over-match for the fever. She changed colour more than once; but she answered me with that forced firmness of gaze, which often indicates determined falsehood. 'She could not imagine who could do such a thing. She could not believe that the animal was poisoned. She did not suppose that any of the servants would venture. In short, she was persuaded that Fido died a natural death.' 'That shall be examined into,' said I, still looking at her in stern enquiry. Again she changed colour, and resumed her denials, but with a more restless and evasive aspect. Presently my glance followed hers to some papers which lay upon the table. I saw her as if by accident cover them with her hand, then dexterously throw them upon the ground; and she was just endeavouring to conceal them with her foot when I snatched up one of them. I observed that it had been the envelope of a small parcel; and turning the reverse, saw that it was marked with the word 'arsenic.' Dumb for a moment with unutterable scorn, I merely presented the paper to Mrs Boswell, and hearing her stammer out some lying explanation, turned in disgust away. But indignation again supplied me with words. 'Find another instructor for your child, Mrs Boswell,' said I; 'I will no longer tell her to despise treachery, and falsehood, and cruelty, lest I teach her to scorn her mother.' Then, without waiting reply, I left the room.
