Model response

Rain hammered Blackthorn Manor as guests gathered for the masquerade.  

At midnight, the chandelier flickered, and every mask turned upward.  

Then a scream sliced through the ballroom, silencing rehearsed laughter.  

Sir Alistair Vane lay beneath portraits, crimson staining his waistcoat.  

His silver key was missing, though his fist remained clenched.  

Detective Mara Quill arrived before anyone dared touch the body.  

She noticed wet footprints leading from corpse toward locked library.  

Outside, thunder concealed the sound of someone quietly fleeing nearby.  

Mara smiled, because murderers often mistook storms for accomplices tonight.
