By Nightfall

Peter and Rebecca Harris: mid-forties denizens of Manhattan’s SoHo, nearing the apogee of committed careers in the arts - he a dealer, she an editor. With a spacious loft, a college-age daughter in Boston, and lively friends, they are admirable, enviable contemporary urbanites with every reason, it seems, to be happy. Then Rebecca’s much younger look-alike brother, Ethan (known in the family as Mizzy, "the mistake"), shows up for a visit. A beautiful, beguiling twenty-three-year-old with a history of drug problems, Mizzy is wayward, at loose ends, looking for direction. And in his presence, Peter finds himself questioning his artists, their work, his career - the entire world he has so carefully constructed.
