Model response

Rain swept across Marlowe Manor as midnight bells began tolling.  
Detective Elin Ward arrived, smelling smoke from burned curtains earlier.  
The victim, Sir Cedric, lay beneath a shattered chandelier silently.  
His throat bore punctures, yet no weapon remained anywhere nearby.  
Guests gathered behind velvet curtains, whispering about his secret debts.  
Lady Maren insisted suicide, but Elin noticed bruised knuckles too.  
Marlowe’s butler swore an alibi, staring at candle shadows steadily.  
In the hearth, a ledger burned, leaving only charred pages.  
Elin vowed to follow clues, before dawn erased every trace.
