The specialist's hat makes a noise like an agouti; The specialist's hat makes a noise like a collared peccary; The specialist's hat makes a noise like a white-lipped peccary; The specialist's hat makes a noise like a tapir; The specialist's hat makes a noise like a rabbit; The specialist's hat makes a noise like a squirrel; The specialist's hat makes a noise like a curassow; The specialist's hat moans like a whale in the water; The specialist's hat moans like the wind in my wife's hair; The specialist's hat makes a noise like a snake; I have hung the hat of the specialist upon my wall.

The reason that Claire and Samantha have a babysitter is that their father met a woman in the woods. He is going to see her tonight, and they are going to have a picnic supper and look at the stars. This is the time of year when the Perseids can be seen, falling across the sky on clear nights. Their father said that he has been walking with the woman every afternoon. She is a distant relation of Rash and besides, he said, he needs a night off and some grownup conversation.

Mr. Coeslak won't stay in the house after dark, but he agreed to find someone to look after Samantha and Claire. Then their father couldn't find Mr. Coeslak, but the babysitter showed up precisely at seven o'clock. The babysitter, whose name neither twin quite caught, wears a blue cotton dress with short floaty sleeves. Both Samantha and Claire think she is pretty in an old- fashioned sort of way.

They were in the library with their father, looking up Mulatuppu in the red leather atlas, when she arrived. She didn't knock on the front door, she simply walked in and then up the stairs, as if she knew where to find them.

Their father kissed them good-bye, a hasty smack, told them to be good and he would take them into town on the weekend to see the Disney film. They went to the window to watch as he walked into the woods. Already it was getting dark and there were fireflies, tiny yellow-hot sparks in the air. When their father had entirely disappeared into the trees, they turned around and stared at the babysitter instead. She raised one eyebrow. "Well," she said. "What sort of games do you like to play?"

Widdershins around the chimneys, Once, twice, again.

The spokes click like a clock on the bicycle; They tick down the days of the life of a man.

First they played Go Fish, and then they played Crazy Eights, and then they made the babysitter into a mummy by putting shaving cream from their father's bathroom on her arms and legs, and wrapping her in toilet paper. She is the best babysitter they have ever had.

At nine-thirty, she tried to put them to bed. Neither Claire nor Samantha wanted to go to bed, so they began to play the Dead game. The Dead game is a let's pretend that they have been playing every day for 274 days now, but never in front of their father or any other adult. When they are Dead, they are allowed to do anything they want to. They can even fly by jumping off the nursery bed and just waving their arms. Someday this will work, if they practice hard enough.

The Dead game has three rules.

One. Numbers are significant. The twins keep a list of important numbers in a green address book that belonged to their mother. Mr. Coeslak's tour has been a good source of significant amounts and tallies: they are writing a tragical history of numbers.

Two. The twins don't play the Dead game in front of grown- ups. They have been summing up the babysitter, and have decided that she doesn't count. They tell her the rules.

Three is the best and most important rule. When you are Dead, you don't have to be afraid of anything. Samantha and Claire aren't sure who the Specialist is, but they aren't afraid of him.

To become Dead, they hold their breath while counting to 35, which is as high as their mother got, not counting a few days.

"You never lived here," Claire says. "Mr. Coeslak lives here."

"Not at night," says the babysitter. "This was my bedroom when I was little."

"Really?" Samantha says. Claire says, "Prove it."

The babysitter gives Samantha and Claire a look, as if she is measuring them: how old, how smart, how brave, how tall. Then she nods. The wind is in the flue, and in the dim nursery light they can see the milky strands of fog seeping out of the fireplace. "Go stand in the chimney," she instructs them. "Stick your hand as far up as you can, and there is a little hole on the left side, with a key in it."

Samantha looks at Claire, who says, "Go ahead." Claire is fifteen minutes and some few uncounted seconds older than Samantha, and therefore gets to tell Samantha what to do. Samantha remembers the muttering voices and then reminds herself that she is Dead. She goes over to the fireplace and ducks inside.

When Samantha stands up in the chimney, she can only see the very edge of the room. She can see the fringe of the mothy blue rug, and one bed leg, and beside it, Claire's foot, swinging back and forth like a metronome. Claire's shoelace has come undone and there is a Band-Aid on her ankle. It all looks very pleasant and peaceful from inside the chimney, like a dream, and for a moment she almost wishes she didn't have to be Dead. But it's safer, really.

She sticks her left hand up as far as she can reach, trailing it along the crumbly wall, until she feels an indentation. She thinks about spiders and severed fingers, and rusty razorblades, and then she reaches inside. She keeps her eyes lowered, focused on the corner of the room and Claire's twitchy foot.

Inside the hole, there is a tiny cold key, its teeth facing outward. She pulls it out, and ducks back into the room. "She wasn't lying," she tells Claire.

"Of course I wasn't lying," the babysitter says. "When you're Dead, you're not allowed to tell lies."

"Unless you want to," Claire says.

Dreary and dreadful beats the sea at the shore.

Ghastly and dripping is the mist at the door.

The clock in the hall is chiming one, two, three, four.

The morning comes not, no, never, no more.

Samantha and Claire have gone to camp for three weeks every summer since they were seven. This year their father didn't ask them if they wanted to go back and, after discussing it, they decided that it was just as well. They didn't want to have to explain to all their friends how they were half-orphans now. They are used to being envied, because they are identical twins. They don't want to be pitiful.

It has not even been a year, but Samantha realizes that she is forgetting what her mother looked like. Not her mother's face so much as the way she smelled, which was something like dry hay and something like Chanel No. 5, and like something else too. She can't remember whether her mother had gray eyes, like her, or grey eyes, like Claire. She doesn't dream about her mother anymore, but she does dream about Prince Charming, a bay whom she once rode in the horse show at her camp. In the dream, Prince Charming did not smell like a horse at all. He smelled like Chanel No. 5. When she is Dead, she can have all the horses she wants, and they all smell like Chanel No. 5.

"Where does the key go to?" Samantha says.

The babysitter holds out her hand. "To the attic. You don't really need it, but taking the stairs is easier than the chimney. At least the first time."

"Aren't you going to make us go to bed?" Claire says.

The babysitter ignores Claire. "My father used to lock me in the attic when I was little, but I didn't mind. There was a bicycle up there and I used to ride it around and around the chimneys until my mother let me out again. Do you know how to ride a bicycle?"

"Of course," Claire says.

"If you ride fast enough, the Specialist can't catch you."

"What's the Specialist?" Samantha says. Bicycles are okay, but horses can go faster.

"The Specialist wears a hat," says the babysitter. "The hat makes noises."

She doesn't say anything else.

When you're dead, the grass is greener Over your grave. The wind is keener.

Your eyes sink in, your flesh decays. You Grow accustomed to slowness; expect delays.

The attic is somehow bigger and lonelier than Samantha and Claire thought it would be. The babysitter's key opens the locked door at the end of the hallway, revealing a narrow set of stairs. She waves them ahead and upwards.

It isn't as dark in the attic as they had imagined. The oaks that block the light and make the first three stories so dim and green and mysterious during the day don't reach all the way up. Extravagant moonlight, dusty and pale, streams in the angled dormer windows. It lights the length of the attic, which is wide enough to hold a softball game in, and lined with trunks where Samantha imagines people could sit, could be hiding and watching. The ceiling slopes down, impaled upon the eight thick- waisted chimney stacks. The chimneys seem too alive, somehow, to be contained in this empty, neglected place; they thrust almost angrily through the roof and attic floor. In the moonlight they look like they are breathing. "They're so beautiful," she says.

"Which chimney is the nursery chimney?" Claire says.

The babysitter points to the nearest right-hand stack. "That one," she says. "It runs up through the ballroom on the first floor, the library, the nursery."

Hanging from a nail on the nursery chimney is a long black object. It looks lumpy and heavy, as if it were full of things. The babysitter takes it down, twirls it on her finger. There are holes in the black thing and it whistles mournfully as she spins it. "The Specialist's hat," she says.

"That doesn't look like a hat," says Claire. "It doesn't look like anything at all." She goes to look through the boxes and trunks that are stacked against the far wall.

"It's a special hat," the babysitter says. "It's not supposed to look like anything. But it can sound like anything you can imagine. My father made it."

"Our father writes books," Samantha says.

"My father did too." The babysitter hangs the hat back on the nail. It curls blackly against the chimney. Samantha stares at it. It nickers at her. "He was a bad poet, but he was worse at magic."

Last summer, Samantha wished more than anything that she could have a horse. She thought she would have given up anything for one-even being a twin was not as good as having a horse. She still doesn't have a horse, but she doesn't have a mother either, and she can't help wondering if it's her fault. The hat nickers again, or maybe it is the wind in the chimney.

"What happened to him?" Claire asks.

"After he made the hat, the Specialist came and took him away. I hid in the nursery chimney while it was looking for him, and it didn't find me."

"Weren't you scared?"

There is a clattering, shivering, clicking noise. Claire has found the babysitter's bike and is dragging it towards them by the handlebars. The babysitter shrugs. "Rule number three," she says.

Claire snatches the hat off the nail. "I'm the Specialist!" she says, putting the hat on her head. It falls over her eyes, the floppy shapeless brim sewn with little asymmetrical buttons that flash and catch at the moonlight like teeth. Samantha looks again and sees that they are teeth. Without counting, she suddenly knows that there are exactly 52 teeth on the hat, and that they are the teeth of agoutis, of coatimundis, of white-lipped peccaries, and of the wife of Charles Cheatham Rash. The chimneys are moaning, and Claire's voice booms hollowly beneath the hat. "Run away, or I'll catch you. I'll eat you!"

Samantha and the babysitter run away, laughing as Claire mounts the rusty, noisy bicycle and pedals madly after them. She rings the bicycle bell as she rides, and the Specialist's hat bobs up and down on her head. It spits like a cat. The bell is shrill and thin, and the bike wails and shrieks. It leans first towards the right and then to the left. Claire's knobby knees stick out on either side like makeshift counterweights.

Claire weaves in and out between the chimneys, chasing Samantha and the babysitter. Samantha is slow, turning to look behind. As Claire approaches, she keeps one hand on the handlebars and stretches the other hand out towards Samantha. Just as she is about to grab Samantha, the babysitter turns back and plucks the hat off Claire's head.

"Shit!" the babysitter says, and drops it. There is a drop of blood forming on the fleshy part of the babysitter's hand, black in the moonlight, where the Specialist's hat has bitten her.

Claire dismounts, giggling. Samantha watches as the Specialist's hat rolls away. It picks up speed, veering across the attic floor, and disappears, thumping down the stairs. "Go get it," Claire says. "You can be the Specialist this time."

"No," the babysitter says, sucking at her palm. "It's time for bed."

When they go down the stairs, there is no sign of the Specialist's hat. They brush their teeth, climb into the ship-bed, and pull the covers up to their necks. The babysitter sits between their feet. "When you're Dead," Samantha says, "do you still get tired and have to go to sleep? Do you have dreams?"

"When you're Dead," the babysitter says, "everything's a lot easier. You don't have to do anything that you don't want to. You don't have to have a name, you don't have to remember. You don't even have to breathe."

She shows them exactly what she means.

When she has time to think about it (and now she has all the time in the world to think), Samantha realizes with a small pang that she is now stuck indefinitely between ten and eleven years old, stuck with Claire and the babysitter. She considers this. The number 10 is pleasing and round, like a beach ball, but all in all, it hasn't been an easy year. She wonders what 11 would have been like. Sharper, like needles maybe. She has chosen to be Dead, instead. She hopes that she's made the right decision. She wonders if her mother would have decided to be Dead, instead of dead, if she could have.

Last year they were learning fractions in school, when her mother died. Fractions remind Samantha of herds of wild horses, piebalds and pintos and palominos. There are so many of them, and they are, well, fractious and unruly. Just when you think you have one under control, it throws up its head and tosses you off. Claire's favorite number is 4, which she says is a tall, skinny boy. Samantha doesn't care for boys that much. She likes numbers. Take the number 8 for instance, which can be more than one thing at once. Looked at one way, 8 looks like a bent woman with curvy hair. But if you lay it down on its side, it looks like a snake curled with its tail in its mouth. This is sort of like the difference between being Dead, and being dead. Maybe when Samantha is tired of one, she will try the other.

On the lawn, under the oak trees, she hears someone calling her name. Samantha climbs out of bed and goes to the nursery window. She looks out through the wavy glass. It's Mr. Coeslak. "Samantha, Claire!" he calls up to her. "Are you all right? Is your father there?" Samantha can almost see the moonlight shining through him. "They're always locking me in the tool room. Goddamn spooky things," he says. "Are you there, Samantha? Claire? Girls?"

The babysitter comes and stands beside Samantha. The babysitter puts her finger to her lip. Claire's eyes glitter at them from the dark bed. Samantha doesn't say anything, but she waves at Mr. Coeslak. The babysitter waves too. Maybe he can see them waving, because after a little while he stops shouting and goes away. "Be careful," the babysitter says. "He'll be coming soon. It will be coming soon."

She takes Samantha's hand and leads her back to the bed, where Claire is waiting. They sit and wait. Time passes, but they don't get tired, they don't get any older.

Who's there?

Just air.

The front door opens on the first floor, and Samantha, Claire, and the babysitter can hear someone creeping, creeping up the stairs. "Be quiet," the babysitter says. "It's the Specialist."

Samantha and Claire are quiet. The nursery is dark and the wind crackles like a fire in the fireplace.

"Claire, Samantha, Samantha, Claire?" The Specialist's voice is blurry and wet. It sounds like their father's voice, but that's because the hat can imitate any noise, any voice. "Are you still awake?"

"Quick," the babysitter says. "It's time to go up to the attic and hide."

Claire and Samantha slip out from under the covers and dress quickly and silently. They follow her. Without speech, without breathing, she pulls them into the safety of the chimney. It is too dark to see, but they understand the babysitter perfectly when she mouths the word, Up. She goes first, so they can see where the finger-holds are, the bricks that jut out for their feet. Then Claire. Samantha watches her sister's foot ascend like smoke, the shoelace still untied.

"Claire? Samantha? Goddammit, you're scaring me. Where are you?" The Specialist is standing just outside the half-open door. "Samantha? I think I've been bitten by something. I think I've been bitten by a goddamn snake." Samantha hesitates for only a second. Then she is climbing up, up, up the nursery chimney.

After a while, everyone had become a zombie.

So they went for a swim.

MONSTER.

NO ONE IN Bungalow 6 wanted to go camping. It was raining, which meant that you had to wear garbage bags over your backpacks and around the sleeping bags, and even that wouldn't help. The sleeping bags would still get wet. Some of the wet sleeping bags would then smell like pee, and the tents already smelled like mildew, and even if they got the tents up, water would collect on the ground cloths. There would be three boys to a tent, and only the boy in the middle would stay dry. The other two would inevitably end up squashed against the sides of the tent, and wherever you touched the nylon, water would come through from the outside.

Besides, someone in Bungalow 4 had seen a monster in the woods. Bungalow 4 had been telling stories ever since they got back. It was a no-win situation for Bungalow 6. If Bungalow 6 didn't see the monster, Bungalow 4 would keep the upper hand that fate had dealt them. If Bungalow 6 did see a monster-but who wanted to see a monster, even if it meant that you got to tell everyone about it? Not anyone in Bungalow 6, except for James Lorbick, who thought that monsters were awesome. But James Lorbick was a geek and from Chicago and he had a condition that made his feet smell terrible. That was another thing about camping. Someone would have to share a tent with James Lorbick and his smelly feet.

And even if Bungalow 6 did see the monster, well, Bungalow 4 had seen it first, so there was nothing special about that, seeing a monster after Bungalow 4 went and saw it first. And maybe Bungalow 4 had pissed off that monster. Maybe that monster was just waiting for more kids to show up at Honor Lookout where all the pine trees leaned backwards in a circle around the bald hump of the hill in a way that made you feel dizzy when you lay around the fire at night and looked up at them.

"There wasn't any monster," Bryan Jones said, "and anyway if there was a monster, I bet it ran away when it saw Bungalow 4." Everybody nodded. What Bryan Jones said made sense. Everybody knew that the kids in Bungalow 4 were so mean that they had made their counselor cry like a girl. The Bungalow 4 counselor was a twenty-year-old college student named Eric who had terrible acne and wrote poems about the local girls who worked in the kitchen and how their breasts looked lonely but also beautiful, like melted ice cream. The kids in Bungalow 4 had found the poetry and read it out loud at morning assembly in front of everybody, including some of the kitchen girls.

Bungalow 4 had sprayed a bat with insect spray and then set fire to it and almost burned down the whole bungalow.

And there were worse stories about Bungalow 4.

Everyone said that the kids in Bungalow 4 were so mean that their parents sent them off to camp just so they wouldn't have to see them for a few weeks.

"I heard that the monster had big black wings," Colin Simpson said. "Like a vampire. It flapped around and it had these long fingernails."

"I heard it had lots of teeth."

"I heard it bit Barnhard."

"I heard he tasted so bad that the monster puked after it bit him."

"I saw Barnhard last night at dinner," Colin Simpson's twin brother said. Or maybe it was Colin Simpson who said that and the kid who was talking about flapping and fingernails was the other twin. Everybody had a hard time telling them apart. "He had a Band-Aid on the inside of his arm. He looked kind of weird. Kind of pale."

"Guys," their counselor said. "Hey guys. Enough talk. Let's pack up and get going." The Bungalow 6 counselor was named Terence, but he was pretty cool. All of the kitchen girls hung around Bungalow 6 to talk to Terence, even though he was already going out with a girl from Ohio who was six foot two and played basketball. Sometimes before he turned out the lights, Terence would read them letters that the girl from Ohio had written. There was a picture over Terence's camp bed of this girl sitting on an elephant in Thailand. The girl's name was Darlene. Nobody knew the elephant's name.

"We can't just sit here all day," Terence said. "Chop chop."
