Model response

AI
The body lay sprawled across the Persian rug, a dark stain spreading from beneath the silent chest by the fireplace. Only the grandfather clock in the hall marked time with its steady, ominous tick-tock throughout the utterly still dark night. The detective's flashlight beam finally found the body, illuminating the pale face and wide, staring eyes of the cold victim. A silver letter opener protruded from his chest, its ornate handle suddenly gleaming under the detective's very powerful flashlight beam. There was obviously no sign of a struggle in the meticulously arranged study filled with expensive books and global artifacts.
