Irvine Welsh, the Scottish novelist, was in town recently to read from his new book, "Porno," which is due out in the fall. "Porno" is the sequel to "Trainspotting," Welsh's first novel, and, like "Trainspotting," "Porno" is not merely set in the drug-infested schemes and public houses of Edinburgh but written in its Port o' Leith dialect; sometimes ye cannae hardly feckin understan a word ay it.

"Ah've no been tae bed yet. This is Thursday night, aye?" Welsh, who is forty-three, had arrived in New York almost twenty-four hours earlier, with three of his old mates. They had known one another for yonks--since they were teen-age hooligans. Now, having already consumed a great deal of bevvy, Welsh was wearing a short-sleeved Hawaiian shirt and drinking Heinekens in a booth at Rudy's, a bar on Ninth Avenue.
