In the heart of London, under the dim streetlights, a chilling scream echoed. The clock struck midnight, its solemn chime piercing the silent night. Rain drizzled, casting eerie shadows on the cobblestone streets. A figure lay motionless, obscured by the foggy darkness. Blood seeped slowly, staining the damp pavement crimson. Beside the body, a shattered vase hinted at a struggle. A single rose, its petals scattered, lay nearby. The scent of perfume lingered, a haunting reminder of the victim. In the distance, sirens began to wail, their sound growing louder. Detective Inspector Lewis stepped out of his car, his face grim. He knew tonight would be a long, grueling night.
