The dim kitchen held a stillness broken suddenly. Silence hung heavy like old forgotten secrets. Coffee stains marked the wooden table surface there. A faint smell lingered near the bright window. Movement caught my eye from the side hallway. Cold fingers gripped my arm suddenly from behind. Blood pooled slowly across the clean floor. The knife gleamed sharply under the kitchen light.
