"You been spying on me?"

"I guess you just a civilized boy, that's all," said Mr. Christmas.

Mack wasn't interested in this man's opinion of him. "So what's your back yard like? Does it just disappear again, like in front?"

"Look and see," said Mr. Christmas. "I don't go back there much."

Mack went to the back door and opened it and looked out onto the patio. There was a rusted barbecue off to one side, and an old-fashioned umbrella-style clothesline with a few clothespins hanging on it like birds perched along a wire. Behind the patio a couple of scraggly-looking orange trees were covered in fruit that had been pecked at by birds or gnawed by squirrels. And the scruffy, patchy, weedy lawn was dotted with rotting fruit.

"All the cheap Mexican labor in LA," said Mack, "and you can't even hire a gardener?"

"You call this a garden?" asked Mr. Christmas.

"Don't you even want to eat these oranges before they rot or the birds and squirrels get them?"

"I've had oranges before. They ain't so much."

"What do you eat?"

"Got a taste for See's Candies," said Mr. Christmas.

"I'm surprised you don't have them growing on trees, the way this house goes."

"I got me a box a few years back. It hasn't run out yet."

"Either that was a big box, or you don't eat much."

"Thirteen years," said Mr. Christmas. "As a matter of fact, I got that box as a birthday present."

"When's your birthday?"

"It wasn't for my birthday," said Mr. Christmas. "You jump to a lot of conclusions."

Mack was tired of riddles. He walked out onto the patio.

Did the trees grow taller?

He stepped back. The orange trees were definitely smaller again.

"I see," he said. "Your front yard gets smaller and smaller till your house just disappears. But the back yard gets bigger and bigger."

"It does what it does," said Mr. Christmas.

Mack walked back toward the trees. Right to the edge of the patio. Curiously, the patio had shrunk down now to a brick path, and when he turned around, the house was farther away than it should have been, and was half hidden among trees and vines that hadn't been there when he crossed the patio. Mr. Christmas stood in the doorway, but he was no longer dressed the way he had been.

Nor was he quite the same man. He was thinner, and his clothes fit snugly, and he looked younger, and his hair was a halo around his head, not filthy dreads at all.

"Who are you?" called Mack.

Mr. Christmas just waved cheerfully. "Don't let anything eat you back there!" he called.

Mack turned back toward the forest—for that's what it was now, not a lawn with trees, but a track through a dense forest and not an orange in sight, though berries grew in profusion beside the path, and butterflies and bees and dragonflies fluttered and hovered and darted over the blossoms of a dozen different kinds of wildflower.

It didn't occur to Mack to be afraid, despite Mr. Christmas's warning. If anything, this forest felt like home to him. Like all his wandering through the neighborhood and Hahn Park his whole life had actually been a search for this place. California was a desert compared to this. Even when the jacaranda bloomed it didn't have this sweet flowery scent in the air, and instead of the dismal brown dirt of Los Angeles there was moss underfoot, and thick loamy black soil in the patches where the path hadn't quite been overgrown.

And water. Los Angeles had a river, but it was penned in like the elephants at the zoo, surrounded by concrete and left dry most of the year. Here, though, the path led alongside a brook that tumbled over mossy stones and had fish darting in the waters, which meant that it never went dry.

Frogs and toads hopped out of the way, and birds flitted across the path in front of him, and beads of water glistened on many a leaf, as if it had rained only a few hours ago—something that never happened in LA in the summer—or perhaps as if the dew had been so heavy that it hadn't all evaporated yet.

Off in the distance, mostly hidden by bushes or vines or trunks of trees, but flashing occasionally as he walked along, there was a tiny light.

Mack left the path and headed toward it. It didn't occur to him at first that he might get lost, once he left the path. He had never been lost in his life. But he had never been in a real forest, either—the open woods of Hahn Park were nothing like this. And when he turned around after only a few steps, he couldn't tell where the path was.

But he could still see the light, flickering among the distant trees.

Now the bushes and branches snagged at his clothes, and sometimes there were brambles, so he had to back out and go around. He found himself on the brink of a little canyon once, and had to turn around and climb down into it, and then search for a place where he could leap over the torrent of water that plunged down the ravine. This place was getting wilder all the time, and yet he still wasn't afraid. He noted the danger, how easily he might get lost, how a person could fall into the current and be swept away to God knows where, just like in his dream, and yet he knew that this wasn't the place or time for his dream to come true, and he would not be harmed here, not today.

Unless, of course, this sense of confidence was part of the magic of the place, luring him on to destruction. Magic was tricky that way, as he knew better than any other soul. What seemed most sweet could be most deadly, what promised happiness could bring you deep and endless grief.

But he went on, clambering up the other side, which was, if anything, steeper than the side that he had climbed down.

When he got to the top again, he could see that there were two lights, not just one, and they were much nearer now. Only a few dozen yards through the bushes and trees—easy passages, mostly—and he was on the edge of a clearing.

The two lights were like old-fashioned lanterns. Glass-sided, with ornate metal lining the panes.

Unlike a lantern, though, there was neither base nor roof to the lights, just glass all the way around.

Nor were there stands holding them up, or wires holding them suspended from above. They simply hung in the air, flickering.

There was no bulb inside, giving light. Nor a wick of any kind, nor a source of fuel. Just a dazzling point of light drifting around inside each lantern, bumping against the glass and changing direction again.

Mack was going to step out into the clearing and look more closely at the lights, but that was when he heard a growl, and saw that a panther, black as night, slunk from shadow to shadow around the forest verge. Its eyes were bright yellow in the lantern light, and at moments Mack thought he could see a red glow even deeper inside the eyes.

The panther growled and bounded suddenly to the middle, directly between the two lights.

Mack took just one more step, not because he was so brave that he did not fear the panther, but because it would have been unbearable not to get a closer look at what the panther's front paws rested on.

It was a corpse, flyblown and rotted. The man had been wearing trousers and a longish shirt, though the shirt had been torn by claws. And instead of a man's head, on his shoulders was the head of a donkey, its eyesockets empty, its fur patchy. Mack had seen squirrels in this condition before; he knew that under the collapsing rib cage there would be nothing, the worms and bacteria having done their work.

This panther must have been here a long time, if it was what killed the donkey-headed man, and the clawing the man's clothes had received suggested that it was.

Whatever the two lanterns were, it was clear enough that the panther did not intend to let anyone near them.

And that was fine with Mack. He was curious, but never so curious that he'd die for an answer.
