“He’s a masterful writer,” says Details editor Daniel Peres (who is Jeff Raines’s age). “It’s a rare pleasure for a young editor to publish something from a real master.” Peres says that he never asked Raines if he would consider writing about the Jayson Blair scandal: “We didn’t want to push it too far,” Peres says. The coup for Details comes during a fertile stretch for the magazine: its ad pages are up 37 percent over last year’s, and Peres has recently signed up a crop of literary contributors such as “Jarhead” author Anthony Swofford and Augusten Burroughs of “Running With Scissors” fame. But it’s unlikely that Raines will appear in the magazine’s pages again. “I don’t expect it to become a regular thing,” says Peres. “It’s not like he’s going to be hard up for work.”
