Adults-only rendition of the lives of two pioneering pornographer-brothers and how one came to murder the other, related in live-wire prose by California journalist McCumber (The San Francisco Examiner, etc.). When Jim Mitchell, 45, shot dead his brother Artie, 43, in 1991, the X-rated film world was stunned: How could this have happened to the dynamic duo of sleaze, who brought the world Ivory Snow-girl Marilyn Chambers and the porn classic Behind the Green Doorg. Drawing on interviews with the Mitcheils' family, friends, and stars, McCumber weaves an unusually lively true-crime chronicle that doubles as a eulogy for innocence lost. For at first, the Mitchelis were innocents of a sort, riding the wave of free love that washed over San Francisco in the late 60's, ""having fun"" turning out porn loops and opening up a theater whose troupe of exotic dancers eventually included many disciples of the notorious guru Rajneesh. In 1972, the Mitchells filmed Behind the Green Door for an unheard-of (for a porn film) $60,000; the film grossed $35 million--and everything changed. Though reveling in his new money and power, Jim kept an even keel--but Attic went hog-wild, living life on a manic, sadistically sexual edge, and wallowing in drugs. McCumber traces Attic's descent in rich style, drawing in-depth portraits of the women he used and abused; and the author's snappy writing continues into his coverage of the trial that ensued when Jim, at last half-crazed himself over his brother's madness, pulled the trigger. (Of the prosecutor, McCumber says, ""He looks tough, intense, feral, predatory. Hell, he looks like a vampire."") Convicted only of manslaughter, today Jim is free on bail, pending appeal. There's a strong moral about the wages of sin here but McCumher doesn't belabor it, instead letting this sad and sleazy story--one of the most gripping yet told about the world of pornography--speak for itself.
