It's been over a year since the terrifying events at the Red House Hotel and everything is back to normal, but Colm is still uneasy. He suspects there's someone evil lurking in the darkness, someone who's planning a terrible revenge. When strange things begin to happen again, he's plunged back into a world of sarcastic detectives and frightening mercenaries, awkward romance and the supernatural. Dealing with street bullies and overprotective parents is nothing compared to this. And to make matters worse, if the master criminal known as The Ghost finds the two remaining Lazarus Keys he will become extremely powerful. More powerful than anyone who has ever lived. The only people who can unravel the mystery and stop The Ghost are Colm, his annoying cousin, The Brute, and a pretty American teenager. Time is running out and the clock is ticking. But how do you stop what you can't see?
