The Carnacki institute exists to Do Something About Ghosts. Lay them to rest, send them packing, or kick their nasty ectoplasmic arses with extreme prejudice.
The institute's operatives are the best of the best. JC Chance: sharp, brave, charming, and almost unbearably arrogant; Melody Chambers: science geek, techno-wizard extraordinaire who keeps the antisupernatual equipment running smoothly; and Happy Jack Palmer: the telepath with the gloomy disposition, the last person anyone would want navigating through their head.
