The Haunting of Toby Jugg is a 1948 psychological thriller novel on an occult theme by English writer Dennis Wheatley, incorporating his usual themes of satanic possession and madness, in what was at that time a fresh situation: a disabled British airman recovering from his experiences in the last stages of World War II, in which he played a part in the bombardment of Germany.
Toby is the heir to a vast fortune and stands to inherit his grandfather's business empire on his twenty-first birthday.
Toby's mother died in childbirth and his father and grandfather were killed in an aircraft accident, leaving his Uncle Paul and Aunt Julia as his only living relatives.
Toby is being haunted by a many-legged, evil and shadowy presence that the young airman comes to believe is the Devil himself.
At first Toby thinks he is hallucinating and then going mad, a view shared by his guardian; finally he believes himself to be at the centre of a sinister plot to cheat him out of his inheritance.
