Fog rolled over the town's cobblestone streets, muffling whispers as the clock struck midnight in the quiet village square alone. Detective Mara entered the dim tavern, eyes scanning the crimson-stained floor where a polished silver dagger glimmered ominously under the. Three patrons lingered: the nervous bartender, the cloaked stranger muttering cryptic verses, and the grieving widow clutching a wilted rose. Rain began pounding the shutters, while outside, a distant wolf howled, echoing the darkness that now claimed the town forever.
