After successfully ridding Peligan of Gallows' murderous spook, Mr Grip, Lil and Nedly turn their attentions to another suspected haunting. But Peligan City has had enough of ghosts and has hired ghost catchers - and Nedly finds himself being hunted.
Luckily, he has Lil on his side. Now an apprentice reporter for the Klaxon, Lil manages to talk her way into a job shadowing intrepid journalist Marsha Quake, who is writing a feature on Ghostcatcher Inc. So with Lil's help, Nedly is able to stay one step ahead, but how long for?
As Nedly develops his own inimitable and slightly haphazard haunting style, hoping to become a hero of Peligan City by protecting the weak and thwarting the powerful, Lil finds herself clashing with her mum, a journalist committed to uncovering the truth at all costs. Lil must protect Nedly by covering his tracks or risk losing him forever. Can she find a way?
