Detective Aris Thorne found the body posed dramatically in the museum's central atrium, beneath a skylight shattered by the storm. The curator lay beside the ancient sarcophagus, a single silver needle protruding from his neck, his expression one of serene surprise. Rainwater pooled on the marble, mingling with the spilled ink from his overturned journal, its final entry detailing a forbidden acquisition. Aris noted the lack of forced entry; the killer had been welcomed, or perhaps had never truly left the echoing halls. The security feed was corrupted, a perfect loop of an empty room played on every screen, a silent, digital ghost. His gaze drifted upward, tracing the path of the fatal projectile, and landed on a gilded gallery, dark and watching. There, tucked into the molding, was a small, white envelope, its starkness a glaring insult to the baroque chaos below.
