Model response

Darkness draped the grand ballroom like a shroud.
Midnight struck the grandfather clock with measured, mournful chimes.
Lady Eleanor shrieked, a sound of sheer, unadulterated terror.
The renowned Duke lay sprawled near the fireplace.
His eyes stared up, vacant, at the gilded ceiling.
A single, deep wound marred his velvet waistcoat.
Silence descended again, thick with unspoken, chilling dread.
Detective Black arrived, his keen eyes surveying everything.
This shocking demise signaled a dangerous new beginning.
Who could commit such a brutal, ghastly crime?
