elevator wasn't working, of course, so I trudged up the stairs. Bare stone steps and no railing, the walls painted industrial grey. I could feel Madman's room long before I got anywhere near it. Like a wild beast, lying in wait around a corner. The feeling grew stronger as I moved warily out onto the second floor. Madman's room lay ahead of me, like a visit to the dentist, like a doctor bearing bad news. The air was bitter cold, my breath steaming thickly before me. I could feel my heart pounding fast in my chest. I walked slowly down the empty corridor, leaning forward slightly, as though forcing my way against an unseen pressure. All my instincts were screaming at me to get out while I still could.

I stopped outside the door. The number matched the one the clerk had given me, but I would have recognised it anyway. The room felt like the pain that wakes you in the middle of the night and makes you think awful words like tumour and poison. It felt like the death of a loved one, or the tone in your lover's voice as she tells you she's leaving you for someone else. The room felt like horror and tragedy, and the slow unravelling of everything you ever held true. Except it wasn't the room. It was Madman.

I didn't know his name. His true, original name. I don't suppose even he did, any more. Names imply an identity and a history, and Madman had torn those up long ago. Now he was a sad, perilous, confused gentleman who had only a nodding relationship with reality. Anyone's reality. What drove him mad in the first place, insane beyond any help or hope of rescue, is a well-known story in the Nightside, and one of the most disturbing. Back in the sixties, Madman was an acid sorcerer, a guru to Timothy Leary, and one of NASA's leading scientists. A genius, with many patents to his name, and an insatiable appetite for knowledge. By the end of the sixties, he'd moved from outer space to inner space, to mysticism and mathematical description theory. He studied and researched for many years, exploring the more esoteric areas of arcane information, trying to discover a way to view Reality as it actually is, rather than the way we all perceive it, through our limited human minds and senses.

Somehow, he found a way to See past the comfortable collective illusion we all live in, and look directly at what lies beneath or beyond the world we know. Whatever it was he Saw in that endless moment, it destroyed his sanity, then and forever. Either because baseline Reality was so much worse, or so much better, than what we believe reality to be. Unbelievable horror or beauty, I suppose both are equally upsetting ideas. These days Madman lives in illusions, and doesn't care. The difference between him and us is that he can sometimes choose his illusions. Though sometimes, they choose him.

Madman can be extremely dangerous to be around. He doesn't believe what he sees is real, so for him it isn't. Around him, the world follows his whims and wishes, his fears and his doubts, reality reordering itself to follow his drifting thoughts. Which can be helpful, or confusing, or scary, because he doesn't necessarily believe in you, either. He can change your personality or your history without your even noticing. And people who annoy or threaten him sufficiently tend to get turned into things. Very unpleasant things. So mostly people just let him wander wherever he wants to go and do whatever he feels like doing. It's safer that way. It helps that Madman doesn't want to do much. People who try to use him tend to come to bad ends.

And here I was standing outside his door, breathing hard, sweating, clenching my hands into fists as I tried to summon up the courage to knock. I was taking a hell of a risk in talking to him, and I knew it. I hadn't been this scared since I faced up to Jessica Sorrow the Unbeliever; and I'd had a sort of weapon to use against her. All I had to set against Madman were my wits and my quick thinking. And even I wouldn't have bet on me. Still, at least Madman came with his own warning signals. For reasons probably not even known to himself, Madman came complete with his own personal sound track; music from
