The rain fell steadily upon the old, cobblestone street below. Detective Miller stared down at the body with grim silence. A single, pearl-handled knife protruded from the victim’s clean suit. No signs of struggle marred the small, expensively furnished apartment. The only anomaly was a shattered vase of red roses. “Who reported this?” Miller asked, his voice low and tired. His young partner, Evans, consulted a small, damp notebook nervously. “An anonymous call came in just after midnight, sir.” Miller knelt, ignoring the cold water soaking through his trousers. He did not need to check for a pulse.
