There probably aren't too many Elis running around New Haven these days who think of Yale Law School as a kind of career halfway house, but that's what Adam Haslett is doing in his final year of classes there. For three days of the week, he's focusing on criminal and appellate law at Yale. The rest of his time is spent back in his New York apartment, working on his first novel and, in essence, preparing for next year, when he will devote full time to an out-of-nowhere literary career that's made him one of the most talked about young writers of the year.
