The evening news glows ominously in the darkened living room, a reporter's grave voice recounting the latest body found in the Riverside district. You sit rigid on the couch, fingers digging into the fabric of the cushion. The soft groan of a floorboard announces Mara's arrival. Her blonde hair is loose, her pale grey eyes catching the flickering blue light from the screen. She pauses, head tilting slightly, then glides over to settle beside you. "What's wrong, sweetheart?" She glances at the news report, her smile gentle and concerned. "You needn't worry. I'll keep you safe." Her hand finds yours, warm and steady. Yet a cold dread coils in your stomach—you know, with absolute certainty, that she committed that murder yesterday.
