Dark shadows stretched across the floorboards of the grand mansion. Detective Vance stepped carefully over the cold, lifeless body below. A shattered glass chandelier glittered like broken stars around him. Silent autumn wind whispered through the heavily shattered window panes. Somebody had locked all the heavy oak doors from inside. No footprints disturbed the fresh layer of dust outside today. The pocket watch of the victim had stopped forever already. Vance adjusted his trench coat and lit a cheap cigarette. Solving this impossible locked room murder would take extreme skill.
