The rain soaked the cobblestone streets. A scream shattered the midnight silence. The body lay beneath the lamplight. A single shoe rested nearby. Inspector Grey arrived within minutes. He knelt beside the dead man. The victim's face was unfamiliar. No identification could be found. A faint scent of roses lingered. This case would test his skills.
