Rain tapped softly against the window as dawn slowly broke. Detective Harper arrived quietly, eyeing the bloodstained knife on table. The elderly woman's eyes stared, her expression frozen in silent scream. A shattered clock lay beneath, time frozen, history lost forever here. Footsteps echoed outside, perhaps neighbors or distant sirens approaching quickly. The house's silence whispered secrets, shadows hiding stories long untold. Harper knelt carefully, searching for clues among scattered papers and dust. A gold locket clutched tightly, revealing a faded, torn photograph inside. Outside, heavy clouds hid the sun, casting darkness over everything. Unseen by all, secrets lurked beneath the calm, waiting to be uncovered.
