Edition details
Book Summary
Satan descends to Earth in human form as Henry Wondergood, seeking amusement and deception, but instead becomes entangled in love, betrayal, and humiliation at the hands of humans. Through his diary, he records his disillusionment with humanity, ultimately discovering that earthly evil and suffering surpass even his own infernal designs.
Bored with Hell, Satan assumes the identity of American billionaire Henry Wondergood and begins a diary aboard a ship to Rome, accompanied by his devil-secretary Irwin Toppi. In Rome, he meets the enigmatic Thomas Magnus and the Madonna-like Maria, experiencing an unfamiliar calm and admiration. Magnus warns him of Cardinal X, and Satan accepts the burden of human suffering. As Satan falls in love with Maria, Magnus reveals her soullessness and manipulative nature, subjecting Satan to a cruel psychological trial. Magnus steals Satan’s billions and orchestrates a public humiliation, forcing Satan to confront his own vulnerability. The narrative culminates in Satan’s realization that human greed, betrayal, and absurdity outwit even the Prince of Lies, leaving him disillusioned and questioning the nature of evil itself.

Mr. Henry Wondergood
An Illinois gentleman abroad who keeps confessing he is Satan in human form, and whose loneliness on the Atlantic is so vast he must write it down.
Maria
A young Roman woman with a gaze as clear as the Campagna sky, whose harp and voice turn Wondergood into a taut, trembling string.
Mr. Toppi
The unbribable, good, poor Toppi — a servant whose plain decency becomes the quiet measure against which grand diabolical schemes are taken.
Satan
The devil himself, ten days into wearing a human body, who finds words, logic, and loneliness far harder to bear than hell ever was.
Cardinal X.
