Crooked Little Vein by Warren Ellis

A burnt-out private investigator is hired by a mysterious government operative to track down a bizarre lost artifact — supposedly the nation’s original constitution printed on a pornographic tissue — and his cross-country search becomes a hallucinatory, often grotesque road trip through the margins of American life, exposing seedy subcultures, grotesque violence, absurdist encounters, and darkly comic distortions of politics, sex, and media; the journey serves as a fiercely satiric, transgressive meditation on modern America’s hypocrisies and decay.
