"Not all celebrities who disappear retire into gated-community comfort in Surrey and, contrary to the lie we are sold, fame is no cushion against falling between the cracks. Slattery is charming company – sweet, solicitous, his brain somehow still sharp despite his best efforts to blunt the thoughts that tormented him. He gave up the coke around the millennium when his beloved mother found some in his flat and he was mortified into abstinence. He couldn’t afford it now anyway. When I ask what his plans are this week, he says: "Buy some food, because we've run out. But we're waiting for money to come in from jobs and that often takes a while. So just make it to the weekend." It is very hard to not measure the distance between what is, what was and what should have been. He does still drink and, yes, he knows it would be better if he stopped completely, but he doesn't think he has the strength to do that. I tell him I am worried that performing will make him drink more. "I've been quite strict with myself so far," he says. "But there have been times when I've thought: 'I can't go on stage, I need that half bottle of vodka right now.' I’m getting better, but there's still some way to go.""
