The boundaries of that dark and secret place, the Nightside, lie entirely contained within the city of London. And in that sick and magical place, gods and monsters, men and spirits, go about their very private business, chasing dreams and nightmares you won’t find anywhere else, marked down at sale price and only slightly shop-soiled. You want to summon up a demon or have sex with an angel? Sell your soul or someone else’s? Change the world for the better or just trade it in for something different? The Nightside lies waiting to oblige you, with open arms and a nasty smile. And yet within the Nightside there are many different lands and principalities, many private kingdoms and domains, and even more private heavens and hells.

One such place is Griffin Hall, where the immortals live.

My name is John Taylor. I’m a private eye, specialising in cases of the weird and uncanny. I don’t solve murders, I don’t do divorce work, and I wouldn’t recognise a clue if you held it up before my face and said Look, this is a clue. I do have a special gift for finding things, and people, so mostly that’s what I do. But basically I’m a man for hire, so sometimes that means I have to go where the money is.

I drove my car along the long, narrow road that spiralled up through the primordial jungle surrounding Griffin Hall. Except it wasn’t really my car, and I wasn’t actually driving. I’d borrowed Dead Boy’s futuristic car, to make a better impression. It was a long, silver bullet with many wondrous features, which had fallen into the Nightside from the future, via a Timeslip. It adopted Dead Boy as its owner and occasional driver. I get the impression he wasn’t given much of a choice. I just sat back in the driving seat, enjoyed the massage function, and let the car drive itself. Probably had faster reactions than me anyway. I knew better than to try to touch any of the controls; the last time I even let my hands rest on the steering wheel, the car gave me a warning electric shock.

Griffin Hall stood at the top of a great hill, in the middle of extensive grounds surrounded by high stone walls, protected by all the very latest scientific and magical defences. The huge wrought-iron gates were guaranteed impenetrable unless you had a current invitation, and you could get turned to stone just for leaning on the bell too hard. Griffin Hall, inside the Nightside, but not part of it. The Griffin family valued their privacy, and didn’t care whom they had to maim, mutilate, or murder to ensure it. Only the very important and the very privileged were ever invited to visit the Griffins at home. Their occasional parties were the biggest and brightest in the Nightside, the very height of the Social Scene; and you weren’t anybody if you didn’t have your invitation weeks in advance. I’d never been here before. For all my chequered and even infamous background, I’d never been important enough to catch the Griffins’ eye, until now. Until they needed me to do the one thing no-one else could do.

I wondered who or what had gone missing, so completely and so thoroughly that not even the mighty Griffins, with all their resources, could find it.

What had once been a truly massive and elegant garden, sprawling up the high sides of the hill, had been left neglected, then abandoned, possibly for centuries. It had fallen into a rioting jungle of assorted and unnatural vegetation, including some plants so ancient they’d been declared extinct outside the Nightside, along with others so strange and distorted they had to have been brought in from other dimensions. A great dark jungle of towering trees and mutant growths, pressed tight together and crowding right up to the edges of the single narrow road. The trees rose high enough to block out the starry expanse of the eternal night sky, leaning out over the road so their interlocking branches formed a canopy, a shadowy green tunnel through which I drove deeper and deeper into the heart of darkness.

They say he raised the hill and the Hall in a single night…But then, they say a lot of things about Jeremiah Griffin.

The car’s headlamps blazed bright as the sun, but the stark scientific light couldn’t seem to penetrate far into the verdant growth on either side of the road. Instead, thick motes of pollen drifted between the trees, big as tennis balls, glowing phosphorescent blue and green. Occasionally, one would burst into a spectacular fireworks display, illuminating the narrow trails and shifting jungle interior with flares and flashes of vivid light.

Some of the plants turned to watch as the car glided smoothly past them.

There were trees with trunks big as houses, their dark, mottled bark glistening wetly in the uncertain light. Heavy, swollen leaves, red as blood, pulsed gently on the lowering branches. Huge flowers blossomed, big as hedges, garish as Technicolor, petals thick and pulpy like diseased flesh. Hanging vines fell like bead curtains over the narrow trails, shivering and trembling like dreaming snakes. Now and again some small scuttling thing would brush up against the tips of the liana, and they would snap and curl around the helpless creature and haul it up, kicking and screaming, into the darkness above. The squealing would stop abruptly, and blood would drip down for a while. Green leafy masses with purple flowers for eyes and rings of thorns for teeth lurched and crashed along the narrow paths, stopping at the very edge of the road to shake their heavy bodies defiantly at the intrusion of light into their dark domain.

I’d hate to be the Griffins’ gardener. Probably have to go pruning armed with a cattle prod and a flame-thrower. As the car drove on, I thought I saw something that might have been a gardener, leaning patiently on a wooden rake at the side of the road to watch me go by. He looked like he was made out of green leaves.

The road rose before me, growing steadily steeper as I approached the summit, and Griffin Hall. The jungle was full of ominous sounds, deep grunts and sibilant rustlings, and the occasional quickly stifled scream. Everything in the jungle seemed to be moving slowly, stirring and stretching as though waking from a deep sleep, disturbed by the intruder in their midst. I was safe, of course. I’d been personally summoned by Jeremiah Griffin himself. I had the current passWords. But I didn’t feel safe. The car’s windows were all firmly closed, and the future vehicle had more built-in weapons than some armies, but still I didn’t feel safe. Being simply a passenger made me feel…helpless. I’ve always preferred to protect myself rather than rely on others. I trust my own capabilities.

A thrashing mass of barbed vines lurched suddenly into the middle of the road, stretching out to block my way. There wasn’t time to slow, never mind stop, and the living barrier looked heavy and solid enough to stop a tank. I braced myself for the impact, and at the last moment a roaring circular buzz-saw rose up out of the car’s bonnet. We slammed into the thorny mass at full speed, and the howling saw tore right through it, spraying green leafy fragments in all directions. Many of them were still twitching. The great green thing screamed shrilly, its thorns trailing harmlessly along the car’s armoured sides as we punched through the green mass and out the other side.

Long, twisting branches lowered themselves into the road ahead, any one of them big enough to snatch up the car and feed it to the overhead canopy. The buzz-saw sank back into the bonnet, and twin flame-throwers rose up in its place. Vicious flames roared out to attack the branches, their flaring light bright and clean against the dark. The heavy branches shook and shuddered as the flames took hold, and they shrank back from the car. We drove on through the opening gap, while the burning branches tried to beat out the flames by slamming themselves repeatedly against the road with terrific force.
