The wind howled beneath a sky dark with rain clouds. Detective Fiona Reed stepped out of her unmarked police car. Yellow tape stretched around the scene like a macabre ribbon. The victim lay face down on the wet garden soil. Blood had seeped into the earth, turning mud crimson red. Fiona crouched beside the body, her eyes narrowing intently. "Time of death, approximately four hours ago," the coroner said. A pearl necklace glinted from beneath the woman's pale neck. "Who would want to kill the mayor's beloved only daughter?" Officer Jenkins approached with a small item in his hand. "Found this hidden in the rose bushes beside her body." A monogrammed lighter, engraved with unfamiliar elegant cursive initials. The rain finally broke, washing away footprints around them. Fiona pocketed the evidence, mind racing with possible scenarios. "Someone wanted to ensure she'd never speak again," she muttered.
