Wicked Angel — Taylor Caldwell

Taylor Caldwell's novel, Wicked Angel, is the story of a young boy named Angelo Saint (the fanciful name is the choice of his mother, who spoils him shamelessly). The story begins when the handsome, charming, and almost unnaturally intelligent "Angel" is four, and follows his malevolent career as his childish rages evolve into calculated attempts to eliminate anyone who opposes his goal to be the center of everyone's world. His desperate father, who knows something is wrong but isn't sure what, is told by a psychiatrist friend that Angel is a "textbook psychopath".
