Malcolm and his best friend Dandy aren't like other 10-year-old boys. Malcolm would rather avoid his older sister, experiment in his lab, and read his science magazines than play sports.

Its arrival is the beginning of the boys' new career as Ghost Detectors when they discover a practical-joking poltergeist! Book 1 in the series

Malcolm is hoping his next gadget, the Ecto-Handheld-Automatic-Heat-Sensitive-Laser-Enchanced Ghost Zapper, will work on the ghost haunting the Millers' house! Book 2 in the series.
