Fog clung to Marrow Street as midnight bells faded away.  
Detective Lark arrived quietly, coat soaked, mind sharpening already tonight.  
The manor gate stood open, iron squealing like anxious birds.  
Inside, candles trembled, throwing long shadows across polished floors alone.  
A servant whispered, claiming Lord Wexler had vanished upstairs suddenly.  
Lark followed the sound of weeping to the library door.  
Books lay scattered, and a teacup steamed beside ink stains.  
On the rug, Wexler sprawled, throat marked by cord tight.  
No windows opened, yet winter air curled around his face.  
Lark noted three footprints, all leading inward, none returning ever.  
From behind, someone murmured, asking whether justice still mattered here.
