This fun early-reader chapter book series continues with Tom and friends battling another ghost. Strange and stinky things are happening at Gloomsburg Castle. To begin with, the creepy place is crawling with TIBIGs (tiny biting ghosts). And now it appears that the murderous spirit of a 400-year-old totally moldy baroness has possessed the palace's owner, infecting her with a killer case of hiccups! To put an end to the foul play and dispel this rank, decaying royal for good, count on ghost-busting boy wonder Tom, averagely spooky ghost Hugo, and the ever-resourceful Hetty. Go ghosthunters!
