In the summer of 1998, Walter Kirn - then a young novelist struggling with fatherhood and a dissolving marriage - set out on a peculiar, fateful errand: to personally deliver a crippled hunting dog from an animal shelter in Montana to the New York apartment of one Clark Rockefeller, a secretive young banker and art collector. Thus began a fifteen-year relationship that drew Kirn deep into the fun-house world of an outlandish, eccentric son of privilege who, one day, would be shockingly unmasked as a brazen serial impostor and brutal double-murderer. This is a one-of-a-kind story of an innocent man duped by a real-life Mr Ripley, taking us on a bizarre and haunting journey from the private club rooms of Manhattan to the courtrooms and prisons of Los Angeles.
