Read the excerpt from the strange case of dr. jekyll and mr. hyde. the besiegers, appalled by their own riot and the stillness that had succeeded, stood back a little and peered in. there lay the cabinet before their eyes in the quiet lamplight, a good fire glowing and chattering on the hearth, the kettle singing its thin strain, a drawer or two open, papers neatly set forth on the business table, and nearer the fire, the things laid out for tea; the quietest room, you would have said, and, but for the glazed presses full of chemicals, the most commonplace that night in london. right in the middle there lay the body of a man sorely contorted and still twitching. they drew near on tiptoe, turned it on its back and beheld the face of edward hyde. he was dressed in clothes far too large for him, clothes of the doctor's bigness; the cords of his face still moved with a semblance of life, but life was quite gone: and by the crushed phial in the hand and the strong smell of kernels that hung upon the air, utterson knew that he was looking on the body of a self-destroyer. "we have come too late,” he said sternly, "whether to save or punish. hyde is gone to his account; and it only remains for us to find the body of your master.” how does this excerpt best develop the theme "good will always prevail over evil”?
