The frosted library window catches my gaze as I stumble upon Mrs. Hale’s lifeless form slumped over a crumpled note. A faint alcoholic fumes linger near her clenched fist which grips a broken quill marked with the initial of someone. The old grandfather clock in the corner ticks loudly breaking the silence that hangs heavily over this unexpected ghastly sight.
