"The Angelus."

Door tugged at Richard's sleeve. "That's it! Richard, come on." She ran for the stage.

"Excuse me, sir," said a guard to Richard. "Might we see your invitation?" said another, taking Richard firmly but discreetly by the arm. "And do you have any identification?"

"No," said Richard.

Door was up on the stage. Richard tried to yank free and follow her, hoping that the guards would forget about him. They didn't: now that he had been brought to their attention they were going to proceed to treat him as they might any other shabby, unwashed, somewhat unshaven gate-crasher. The guard who was holding Richard increased his grip on his arm, muttering, "None of that."

Door paused on the stage, wondering how to make the guards let Richard go. Then she did the only thing she could think of. She went over to the microphone, went up on tiptoes, and she screamed, as loudly as she possibly could, into the public-address system. She had a remarkable scream: it could, with no artificial assistance, go through your head like a new power drill with a bone-saw attachment. And amplified . . . It was simply unearthly.

A waitress dropped her tray of drinks. Heads turned. Hands covered ears. All conversation stopped. People stared at the stage in puzzlement and horror. And Richard made a break for it. "Sorry," he said to the stunned guard, as he yanked his arm out of the man's grip, and fled. "Wrong London." He reached the stage, grabbed Door's outstretched left hand. Her right hand touched the Angelus, the enormous cathedral door. Touched it, and opened it.

This time no one dropped any drinks. They were frozen, staring, utterly overwhelmed—and, momentarily, blinded. The Angelus had opened, and light, from behind the door, had flooded the room with radiance. People covered their eyes then, hesitantly, opened them again, and simply stared. It was as if fireworks had been let off in the room. Not indoor fireworks, strange crawling things that sputter and smell bad; nor even the kind of fireworks that you set off in your back yard; but the kind of industrial-strength fireworks that get fired up high enough to cause a potential menace to the airways: the kind of fireworks that end a day at Disney World, or that give the fire marshals headaches at Pink Floyd concerts. It was a moment of pure magic.

The audience stared, entranced and amazed. The only noise to be heard was the gentle, gasping almost-groan of wonderment that people make when they watch fireworks: the sound of awe. Then a grubby young man and a dirty-faced girl in a huge leather jacket walked into the light show and vanished. The door closed, behind them. The light show was over.

And everything was normal again. The guests, and guards, and serving staff, blinked, shook their respective heads, and, having dealt with something entirely outside of their experience, agreed, somehow, without a word, that it had simply never happened. The string quartet began to play once more.

Mr. Stockton walked off, nodding brusquely to various acquaintances as he did so. Jessica walked over, to Clarence. "What," she asked, quietly, "are those security guards doing in here?"

The guards in question were standing among the guests, looking around as if they were themselves unsure what they were doing there. Clarence began to explain just what the guards were doing there; and then he realized he had absolutely no idea. "I'll deal with it," said Clarence, efficiently.

Jessica nodded. She looked out over her party and smiled benignly. It was all going rather well.

Richard and Door walked into the light. And then it was dark, and chill, and Richard was blinking at the retinal afterimage of the light, which left him almost blinded: a ghostly series of orange-green splotches that slowly faded, as his eyes accustomed themselves to the darkness that surrounded them.

They were in a huge hall, carved from rock. Iron pillars, black and rust-dusted, held up the roof, went off into the distant dark, perhaps for miles. From somewhere he could hear the gentle splash of water: a fountain, perhaps, or a spring. Door was still holding his hand, tightly. In the distance, a tiny flame flickered and flared. And another, and then another: it was a host of candles, flickering into flame, Richard realized. And walking toward them, through the candles, was a tall figure, dressed in a simple white robe.

The figure seemed to be moving slowly, but it must have been walking very fast, as it was only seconds before it was standing beside them. It had golden hair and a pale face. It was not much taller than Richard, but it made him feel like a little child. It was not a man; it was not a woman. It was very beautiful. Its voice was quiet. It said, "The Lady Door, yes?"

Door said, "Yes."

A gentle smile. It nodded its head to her, almost humbly. "It is an honor finally to meet you and your companion. I am the Angel Islington." Its eyes were clear and wide. Its robes were not white, as Richard had initially thought: they seemed to have been woven from light.

Richard did not believe in angels, he never had. He was damned if he was going to start now. Still, it was much easier not to believe in something when it was not actually looking directly at you and saying your name. "Richard Mayhew," it said. "You, too, are welcome here, in my halls." It turned away. "Please," it said. "Follow me."

Richard and Door followed the angel through the caverns. The candles extinguished themselves behind them.

The marquis de Carabas strode through the empty hospital, broken glass and old syringes crunching beneath his square-toed black motorcycle boots. He stepped through a double door that led into a back staircase. He went down the stair's, to the cellars beneath the hospital.

He walked through the rooms beneath the building, stepping fastidiously around the heaps of moldering rubbish. He walked through the showers and the toilets, down an old iron staircase, through a wet, swampy place; and then pulled open a half-rotted wooden door, and went inside. He looked around the room in which he found himself; he inspected, with magnificent disdain, the half-eaten kitten and the heap of razor blades. Then he cleared the debris off a chair, sat down, comfortably, luxuriantly, in the dankness of the cellar, and closed his eyes.

Eventually the door to the cellar was opened and people came in.

The marquis de Carabas opened his eyes and yawned. Then he flashed Mr. Croup and Mr. Vandemar a huge smile. "Hello boys," said de Carabas. "I thought it high time I came down here to talk to you in person."

"Do you drink wine?" it asked.

Richard nodded.

"I had a little wine once," said Door, hesitantly. "My father. He. At dinner. Would let us taste it."

The Angel Islington lifted the bottle: it looked like some kind of decanter. Richard wondered if the bottle was made of glass; it refracted and reflected the candlelight so strangely. Perhaps it was some kind of crystal, or one huge diamond. It even made it seem that the wine inside was glowing, as if it were made of light.

The angel took the top off the crystal and poured an inch of the liquid inside it into a wine glass. It was a white wine, but a wine unlike any Richard had ever seen. It threw light around the caverns, like sunlight on a swimming pool.

Door and Richard sat around an age-blackened wooden table, on huge wooden chairs, and said nothing. "This wine," said Islington, "is the last bottle of its kind. I was given a dozen bottles by one of your ancestors."

It handed the glass to Door, and began to pour another inch of the glowing wine from the decanter into another glass. It did this reverently, almost lovingly, like a priest performing a ritual. "It was a welcome gift. This was, oh, thirty, forty thousand years ago. Quite a while ago, at any rate." It passed the wine glass to Richard. "I suppose that you could accuse me of squandering something I should treasure," it told them. "But I receive guests so rarely. And the way here is hard."
