Haunting actually comes naturally to ghosts and the boys have to exert themselves to not do it, because they don’t want to frighten anybody and it might get in the way of cases.
Charles who causes cold spots; Charles who can make a whole room cold enough for the living to see their breath in the middle of summer, if he’s upset enough. Charles who occasionally leaves footprints of muddy water where he walks. Charles who leaves droplets of water running down mirrors after he uses them.
Edwin who has the smell of burning sulfur clinging to him; Edwin who always has the living checking around for a fire. Edwin, whose calculating gaze can make even non-sighted living shiver like they’re being watched. Edwin, who might seem calm, but the electricity surging and fuses blowing gives him away.
Ghosts boys that actually do some haunting.
