Model response

The creaky attic door swings open to reveal a corpse. A frayed pocketwatch ticks loudly beside the cold still form. Crumbled black letter slips from the victim’s limp clenched fist. Dusty raven feathers scatter across blood-spotted wooden attic slats. Faint echoing footsteps draw closer outside the shadowed attic stairs.
