“A modern knight-errant on a quest after evil; grotesque, convincing and chilling.” —The New York Times Book Review Fed up with the excesses of the 1970s, Lancelot Andrews Lamar, a liberal lawyer and distinguished member of the New Orleans gentry, is determined to stop the modern world’s ethical collapse. His quest begins with his wife — an actress who he suspects has been cheating on him for years. Though he initially plans only to gather proof of her infidelity, Lancelot quickly descends into a fog of obsession. And as he crosses the line from sanity into madness, he will try once and for all to purify the world or destroy it in the attempt. Mesmerizing and unforgettable, Lancelot is a masterful story of one man’s collision with the follies of modern culture, and a thought-provoking look at the nature of good and evil
