Parry is the main character, principle protagonist, and later principle antagonist of the novel For Love of Evil, by Piers Anthony. He was born in the thirteen century and intended for use as a sacrifice by a Sorcerer, but the local Abbot intervenes on Parry's behalf, making the Sorcerer adopt and raise him. When he is fifteen, Parry marries and falls in love with Jolie, a pretty fourteen-year-old peasant girl. They are happy for two years, and Parry becomes a powerful wizard. Parry is a white magician and uses his magic to further the good of God. Parry is also an excellent singer and artist and is very intelligent.
When the King of France sends his troops out after heretics, Jolie and the Sorcerer are killed. Perry, heartbroken, flees and heads north. There, Parry falls in league with the Franciscan monks, seeking truth and seeking to do good. Parry then joins the Dominican order, the monks of which focus on the cause, consequences, and problem of evil. Parry becomes a respected individual, helped and aided by the ghost of Jolie. They help avert a Mongolian invasion of Western Europe, and Jolie possesses the body of a peasant girl to make love to Parry. Parry has betrayed his Oath as a monk, and Lucifer takes note, sending Lilah to further corrupt Parry.
Parry, corrupted, becomes an agent of the Devil on earth, helping to fuel the Inquisition. When Lilah and Parry fall in love with each other and Parry refuses to submit to Lucifer, still having good in his heart, Lucifer attempts to do away with them. But Parry topples Lucifer from power with a magic defense spell. Parry then becomes Master of Hell, seeking to reorganize and reform the realm of evil. Later, when Parry attempts to use Lilah to manipulate the Incarnation of War, Mars instead corrupts Lilah.
Parry, meanwhile, learns of a prophecy that could lead to his downfall: an Irish woman named Niobe. Niobe's daughter, Orb, becomes the Incarnation of Nature, Gaea, who falls in love with and marries Parry. To consummate their love, Parry must give up his throne, but in the end, cannot do so. If he does, an even worse ruler will assume control of Hell. Jolie's spirit then returns to possess other willing bodies, to make love to Parry.
