Model response

Rain tapped softly on rooftops.
Detective Vale arrived before dawn.
Police tape circled the mansion.
Inside, candles flickered beside blood.
A grandfather clock stopped suddenly.
The victim faced the window.
One hand clutched crimson roses.
The other held a key.
Vale studied footprints near curtains.
None belonged to the victim.
Behind him, floorboards creaked twice.
Someone whispered, “You came back.”
Vale turned toward the hallway.
Nothing moved beyond the darkness.
Then the clock began ticking.
