Model response

Rain silvered the manor windows, masking footsteps in the gravel below.  
Inside, the clocks stopped together, and Mrs. Vale screamed first.  
Detective Mara Finch arrived, brushing mud from her black coat.  
The study door stood ajar, spilling lamplight across the corridor.  
On the carpet lay Lord Vale, his hand clutching letters.  
A single rose rested beside him, petals darkened by blood.  
No windows were broken, no servants saw anything, and everyone lied.
