But to the great inventor Edison it was the ideal place to test his new advice - a machine to speak to the dead. What he saw there left him shaken, determined to neutralise the strange and dangerous instrument and keep its terrible secret hidden. When Ben and Laura unearth the long buried apparatus and attempt to recreate Edison's experiment, the unwittingly unleash a malevolent force more powerful than anything ever known to Mankind. Too late, they realise they've played straight into the hands of the Master of Evil...A story allegedly based on real events.
