When I heard the sound of glass breaking, my first thought wasn’t shock, or even sadness at the tragic loss of so much great whisky. The words I mouthed to nobody in particular after I watched the bottle of Highland Park 18-year-old Scotch slip from Irvine Welsh’s grasp and crash on the sidewalk were, “At least it wasn’t the 25.” I felt almost no emotion at all. It was as if its fate was written.Welsh, the Edinburgh-born author whose latest book—Skagboys, a prequel to his classic 1993 novel, Trainspotting—was released today, had just left the office and was headed to a black Town Car waiting for him out front. I loved reading Skagboysas I loved reading Trainspotting nearly two decades earlier. I found both to be amazingly detailed and true-feeling stories of growing up, getting in trouble, looking for kicks, and trying to find some meaning in life, and I was thrilled to talk to Welsh about his work. So I’d arranged to meet with him in BlackBook’s second-floor conference room, which overlooks 19th Street. Since I also write about liquor, I thought it would be fun to combine the interview with a spirits tasting.
