Rain hammered the cobblestones as dusk swallowed the narrow alley. Detective Marlowe entered, his trench coat dripping with suspicion today. A single candle flickered behind a bloodstained velvet curtain alone. The body lay twisted, a broken pocket watch ticking still. Marlowe's eyes narrowed, noting the peculiar arrangement of roses nearby. A muffled scream echoed from upstairs, promising answers and danger.
