A thick, persistent fog clung to the London docks like a guilty secret just before the bleak dawn finally broke. During his routine morning patrol, the young constable discovered a male body slumped against a damp, splintered old shipping crate. The victim appeared to be a well-dressed gentleman in his fifties, with a neatly trimmed salt-and-pepper mustache and vacant eyes. A monogrammed silver cigarette case lay open nearby, its contents spilled across the wet, uneven, and particularly filthy cobblestones. The renowned Detective Inspector Grayson arrived, his sharp eyes immediately scanning the grim, fog-shrouded dockside crime scene with practiced ease. He knew, with chilling certainty, this murder would unravel the very highest and most secret echelons of London's elite society.
