Living skeleton. I'd seen a face like that somewhere…

Peake's tongue darted again. He started to rock. Moved his head from side to side. Rolled his neck. Blinked spasmodically. More tongue thrusts.

The mouth had flattened, gone two-dimensional. Moistened by saliva, the lips materialized-port-wine slash in the center of the triangle, vivid against the doughy skin.

It opened again and the tongue extended completely- thick, purplish, mottled, like some cave-dwelling slug.

It hung in the air. Curled. Wagged from side to side. Zipped back.

Out again. In again.

More neck-rolling.

I knew where I'd seen the face. Poster art from my college days. Edvard Munch's The Scream.

Hairless melting man clutching his face in primal mental agony. Peake could have posed for the painting.

His hands remained in his lap, but his upper body swayed, trembled, jerked a few times, seemed about to topple. Then he stopped Righted himself.

Looked in our direction.

He'd butchered the Ardullos at age nineteen, making him thirty-five. He looked ancient.

"Ardis?" said Swig.

No reaction. Peake was staring in our direction but not making contact. He closed his eyes. Rolled his head. Another two minutes of tardive ballet.

Swig gave a disgusted look and waved his hand, as if to say, "You asked for it."

Mik› ignored that and stepped closer. Peake began rocking faster, licking his lips, the tongue emerging, curling, retreating. Several toes on his left foot jumped. His left hand fluttered.

"Ardis, it's Mr. Swig. I've got some visitors for you."

Nothing.

Swig said, "Go ahead, Detective."

No response to "Detective."

I bent and got down at Peake's eye level. Milo did, too. Peake's eyes had remained closed. Tiny waves seemed to ruffle-eyeballs rolling behind gray skin. His chest was white and hairless, freckled with blackheads. Gray nipples- a pair of tiny ash piles. Up close the burning smell was stronger.

Milo said, "Hey," with surprising gentleness.

A few new shoulder tics, tongue calisthenics. Peake rolled his head, lifted his right hand, held it in midair, dropped it heavily.

"Hey," Milo repeated. "Ardis." His face was inches from Peake's. I got closer myself, still smelling the combustion but feeling no heat from Peake's body.

"My name's Milo. I'm here to ask you about Dr. Argent."

Peake's movements continued, autonomic, devoid of intent.

"Claire Argent, Ardis. Your doctor. I'm a homicide detective, Ardis. Homicide."

Not an errant eyeblink.

Milo said, "Ardis!" very loud.

Nothing. A full minute passed before the lids lifted. Halfway, then a full view of the eyes.

Black slots. Pinpoints of light at the center, but no definition between iris and white.

"Claire Argent," Milo repeated. "Dr. Argent. Bad eyes in a box."

The eyes slammed shut. Peake rolled his head, the tongue explored air. One toe jumped, this time on the right foot.

"Bad eyes," said Milo, nearly whispering, but his voice had gotten tight, and I knew he was fighting to keep the volume down. "Bad eyes in a box, Ardis."

Ten seconds, fifteen… half a minute.

"A box, Ardis. Dr. Argent in a box."

Peake's neuropathic ballet continued, unaltered.

"Bad eyes," Milo soothed.

I was looking into Peake's eyes, plumbing for some shred of soul.

Flat black; lights out.

A cruel phrase for mental disability came to mind: "no one home."

Once upon a time, he'd destroyed an entire family, speedily, lustily, a one-man plague.

Taking the eyes.

Now his eyes were twin portholes on a ship to nowhere.

No one home.

As if someone or something had snipped the wires connecting body to soul.

His tongue shot forward again. His mouth opened but produced no sound. I kept staring at him, trying to snag some kind of response. He looked through me-no, that implied too much effort.

He was, I was. No contact.

Neither of us was really there.

His mouth cratered, as if for a yawn. No yawn. Just a gaping hole. It stayed that way as his head craned. I thought of a blind newborn rodent searching for its mother's nipple.

The music from the ceiling switched to "Perfidia," done much too slowly. Ostentatious percussion that seemed to lag behind wan-wan trumpets.

Milo tried again, even softer, more urgent: "Dr. Argent, Ardis. Bad eyes in a box."

The tardive movements continued, random, arrhythmic. Swig tapped his foot impatiently.

Milo stood, knees cracking. I got to my feet, catching an eyeful of the chain on the wall. Coiled, like a sleeping python.

The room smelled worse.

Peake noticed none of it.

No behav. change.

Outside the room, Swig said, "Satisfied?"

Milo said, "Why don't we give Heidi a try with him?"

"You've got to be kidding."

"Wish I was, sir."

Swig shook his head, but he hailed a tech standing across the hall. "Get Heidi Ott, Kurt."

Kurt hustled off and we waited among the inmates. Patients. Did it make a difference what you called them? I started to notice lots of tardive symptoms-a tremor here, lip work there-but nothing as severe as Peake's. Some of the men seemed oriented; others could have been on another planet. Shuffling feet in paper slippers. Food stains on clothing.

Swig went into the nursing station, used the phone, glanced at his watch. He was back just as Heidi Ott came through the double doors.

"Hello, Heidi."

"Sir?"

"Because of the information you provided, Detective Sturgis has been trying unsuccessfully to communicate with Ardis Peake. Since you've got a track record, why don't you give it a shot?"

"Sir, I-"

"Don't worry," said Swig. "Your sense of duty is beyond reproach. The main thing is, let's get to the bottom of this."

"One thing before you go in there. You're sure Peake actually spoke to you-real words, not just grunts."

"Yes, sir."

"Tell me exactly what he said."

Heidi repeated the story.

"And this was the day before Dr. Argent died?"

"Yes, sir."

"Had Peake talked to you before?"

"Not about Dr. Argent.\

"What did he say?"

"Nothing much. Mostly mumbles. Yeah, no, nods, grunts. When we asked him questions." Tug on the ponytail. "Nothing, really. That's why I paid attention to when he did start-"

"You were monitoring his speech."

"Yes, sir. Dr. Argent was hoping she might be able to increase his verbal output. His behavioral output in general."

"I see," said Swig. "Any particular reason she wanted to do that?"

Heidi glanced at us. "Like I told these gentlemen, she said he was a challenge."

A faint, scraping sound grew louder, and we all turned. Paper soles on linoleum. A few of the men in the hall had drifted closer. Swig looked at them and they stopped. Retreated.

He smiled at Heidi. "Looks like you've got the challenge, now."

She went in alone, stayed for twenty minutes, emerged, shaking her head. "How long do you want me to try?"

"That'll be enough," said Swig. "It was probably just an isolated incident. Meaningless rambling. For all we know, he does that when he's alone. Thanks, Heidi. You can get back to work. We'd all better get back to work."

As I drove off the grounds, Milo said, "What the hell turns a human being into thaf!"

"Answer that and you've got the Nobel," I said.

"But we've got to be talking biology, right? No amount of stress can do that." The air-conditioning was on, but sweat dripped offhis nose and spotted his trousers.

"Even in concentration camps people rarely went mad from suffering," I said. "And schizophrenia has the same prevalence in nearly every society-two to four percent. Cultural factors influence how madness is expressed, but they don't cause it."
