Model response

Rain needled Blackthorn Hall's windows.
Guests whispered beneath the chandelier.
A clock swallowed each heartbeat.
Then Lady Harrow screamed upstairs.
Silence flooded the marble foyer.
I found the body smiling.
Blood jeweled the ivory banister.
Someone laughed behind the curtains.
No one admitted leaving dinner.
Outside, thunder erased the footprints.
Inside, suspicion chose its victims.
