Novelist Irvine Welsh found a bunch of notes for his 1993 novel Trainspotting, about the seamy, druggy world of Edinburgh junkies in the 80s, and decided there's enough for a prequel. The prequel will cover the halcyon younger days of his main characters, and their descent: "It's about how Renton and Sick Boy went from being daft young guys just out for the buzz on drugs, to total junkies," he told London's Times.
