Ferron sent a text message. h.e.l.lo, Mother. You wanted to see me? The pause was long, but not as long as it could have been. You"re late, Tamanna. I"ve been trying to reach you all day. I"m in the middle of a run right now.

I"m sorry, Ferron said. Someone was murdered.

Text, thank all the G.o.ds, sucked out the defensive sarcasm that would have filled up a spoken word. She fiddled the bangles she couldn"t wear on duty, just to hear the gla.s.s chime.

She could feel her mother"s attention elsewhere, her distaste at having the unpleasant realities of Ferron"s job forced upon her. That attention would focus on anything but Ferron, for as long as Ferron waited for it. It was a contest of wills, and Ferron always lost. Mother- Her mother pushed up the faceplate on the VR helmet and sat up abruptly. "b.l.o.o.d.y h.e.l.l," she said. "Got killed. That"ll teach me to do two things at once. Look, about the archives-"

"Mother," Ferron said, "I can"t. I don"t have any more savings to give you."

Madhuvanthi said, "They"ll kill me."

They"ll de-archive your virtual history, Ferron thought, but she had the sense to hold her tongue.

After her silence dragged on for fifteen seconds or so, Madhuvanthi said, "Sell the fox."

"He"s mine," Ferron said. "I"m not selling him. Mother, you really need to come out of your make-believe world once in a while-"

Her mother pulled the collar of the VR suit open so she could ruffle the fur of the violet-and-teal striped skinpet nestled up to the warmth of her throat. It humped in response, probably vibrating with a comforting purr. Ferron tried not to judge, but the idea of parasitic pets, no matter how fluffy and colorful, made her skin crawl.

Ferron"s mother said, "Make-believe. And your world isn"t?"

"Mother-"

"Come in and see my world sometime before you judge it."

"I"ve seen your world," Ferron said. "I used to live there, remember? All the time, with you. Now I live out here, and you can too."

Madhuvanthi"s glare would have seemed blistering even in the rainy season. "I"m your mother. You will obey me."

Everything inside Ferron demanded she answer yes. Hard-wired, that duty. Planned for. Programmed.

Ferron raised her right hand. "Can"t we get some dinner and-"

Madhuvanthi sniffed and closed the faceplate again. And that was the end of the interview.

Rightminding or not, the cool wings of hypomania or not, Ferron"s heart was pounding and her fresh clothing felt sticky again already. She turned and left.

When she got back to her own flat, the first thing she noticed was her makeshift wall of furniture partially disa.s.sembled, a chair/shelf knocked sideways, the disconnected and overturned table top now fallen flat.

"Oh, no." Her heart rose into her throat. She rushed inside, the door forgotten- Atop a heap of cushions lay Smoke, proud and smug. And against his soft gray side, his fluffy tail flipped over her like a blanket, curled Chairman Miaow, her golden eyes squeezed closed in pleasure.

"Mine!" she said definitively, raising her head.

"I guess so," Ferron answered. She shut the door and went to pour herself a drink while she started sorting through Indrapramit"s latest crop of interviews.

According to everything Indrapramit had learned, Coffin was quiet. He kept to himself, but he was always willing and enthusiastic when it came to discussing his work. His closest companion was the cat-Ferron looked down at Chairman Miaow, who had rearranged herself to take advantage of the warm valley in the bed between Smoke and Ferron"s thigh-and the cat was something of a neighborhood celebrity, riding on Coffin"s shoulder when he took his exercise.

All in all, a typical portrait of a typical, lonely man who didn"t let anyone get too close.

"Maybe there will be more in the archinformation," she said, and went back to Doyle"s pattern algorithm results one more d.a.m.n time.

After performing her evening practice of kalari payat-first time in three days-Ferron set her furniture for bed and retired to it with her files. She wasn"t expecting Indrapramit to show up at her flat, but sometime around two in the morning, the lobby door discreetly let her know she had a visitor. Of course, he knew she"d upped, and since he had no family and lived in a thin-walled dormitory room, he"d need a quiet place to camp out and work at this hour of the night. There wasn"t a lot of productive interviewing you could do when all the subjects were asleep-at least, not until they had somebody dead to rights enough to take them down to the jail for interrogation.

His coming to her home meant every other resident the block would know, and Ferron could look forward to a morning of being quizzed by aunties while she tried to cram her idlis down. It didn"t matter that Indrapramit was a colleague, and she was his superior. At her age, any sign of male interest brought unEmployed relatives with too much time on their hands swarming.

Still, she admitted him. Then she extricated herself from between the fox and the cat, wrapped her bathrobe around herself, stomped into her slippers, and headed out to meet him in the hall. At least keeping their conference to the public areas would limit knowing glances later.

He"d upped too. She could tell by the bounce in his step and his slightly wild focus. And the fact that he was dropping by for a visit in the dark of the morning.

Lowering her voice so she wouldn"t trouble her neighbors, Ferron said, "Something too good to mail?"

"An interesting potential complication."

She gestured to the gla.s.s doors leading out to the sunfarm. He followed her, his boots somehow still as bright as they"d been that morning. He must polish them in an anti-static gloss.

She kicked off her slippers and padded barefoot over the threshold, making sure to silence the alarm first. The suntrees were furled for the night, their leaves rolled into funnels that channeled condensation to the roots. There was even a bit of chill in the air.

Ferron breathed in gratefully, wiggling her toes in the cultivated earth. "Let"s go up to the roof."

Without a word, Indrapramit followed her up the winding openwork stair hung with bougainvillea, barren and th.o.r.n.y now in the dry season but a riot of color and greenery once the rains returned. The interior walls of the aptblock were mossy and thickly planted with coriander and other Ayurvedic herbs. Ferron broke off a bitter leaf of fenugreek to nibble as they climbed.

At the landing, she stepped aside and tilted her head back, peering up through the potted neem and lemon and mango trees at the stars beyond. A dark hunched shape in the branches of a pomegranate startled her until she realized it was the outline of one of the house monkeys, huddled in sleep. She wondered if she could see the Andromeda Galaxy from here at this time of year. Checking a skymap, she learned that it would be visible-but probably low on the horizon, and not without a telescope in these light-polluted times. You"d have better odds of finding it than a hundred years ago, though, when you"d barely have been able to glimpse the brightest stars. The Heavenly Ganges spilled across the darkness like sequins sewn at random on an indigo veil, and a crooked fragment of moon rode high. She breathed in deep and stepped onto the gra.s.s and herbs of the roof garden. A creeping mint snagged at her toes, sending its pungency wide.

"So what"s the big news?"

"We"re not the only ones asking questions about Dexter Coffin." Indrapramit flashed her a video clip of a pale-skinned woman with red hair bleached ginger by the sun and a crop of freckles not even the gloss of sunblock across her cheeks could keep down. She was broad-shouldered and looked capable, and the ID codes running across the feed under her image told Ferron she carried a warrant card and a stun pistol.

"Contract cop?" she said, sympathetically.

"I"m fine," he said, before she could ask. He spread his first two fingers opposite his thumb and pressed each end of the V beneath his collarbones, a new nervous gesture. "I got my Chicago block maintained last week, and the reprogramming is holding. I"d tell you if I was triggering. I know that not every contract cop is going to decompensate and start a ma.s.sacre."

A ma.s.sacre Indrapramit had stopped the hard way, it happened. "Let me know what you need," she said, because everything else she could have said would sound like a vote of non-confidence.

"Thanks," he said. "How"d it go with your mother?"

"Gah," she said. "I think I need a needle. So what"s the contractor asking? And who"s employing her?"

"Here"s the interesting thing, boss. She"s an American too."

"She couldn"t have made it here this fast. Not unless she started before he died-"

"No," he said. "She"s an expat, a former New York homicide detective. Her handle is Morganti. She lives in Hongasandra, and she does a lot of work for American and Canadian police departments. Licensed and bonded, and she seems to have a very good rep."

"Who"s she under contract to now?"

"Warrant card says Honolulu."

"Huh." Ferron kept her eyes on the stars, and the dark leaves blowing before them. "Top-tier distributed policing, then. Is it a skip trace?"

"You think he was on the run, and whoever he was on the run from finally caught up with him?"

"It"s a working theory." She shrugged. "Damini"s supposed to be calling with some background any minute now. Actually, I think I"ll check in with her. She"s late, and I have to file a twenty-four-hour report with the Inspector in the morning."

With a twitch of her attention, she spun a bug out to Damini and conferenced Indrapramit in.

The archinformist answered immediately. "Sorry, boss," she said. "I know I"m slow, but I"m still trying to put together a complete picture here. Your dead guy buried his past pretty thoroughly. I can give you a preliminary, though, with the caveat that it"s subject to change."

"Squirt," Ferron said, opening her firewall to the data. It came in fast and hard, and there seemed to be kilometers of it unrolling into her feed like an endless bolt of silk. "Oh, dear ... "

"I know, I know. Do you want the executive summary? Even if it"s also a work in progress? Okay. First up, n.o.body other than Coffin was in his flat that night, according to netfeed tracking."

"The other night upon the stair," Ferron said, "I met a man who wasn"t there."

Damini blew her bangs out of her eyes. "So either n.o.body came in, or whoever did is a good enough hacker to eradicate every trace of her presence. Which is not a common thing."

"Gotcha. What else?"

"Doyle picked out a partial pattern in your feed. Two power cuts in places a.s.sociated with the crime. It started looking for more, and it identified a series of brownouts over the course of a year or so, all in locations with some connection to Dr. Coffin. Better yet, Doyle identified the cause."

"I promise I"m holding my breath," Indrapramit said.

"Then how is it you are talking? Anyway, it"s a smart virus in the power grids. It"s draining power off the lab and household sunfarms at irregular intervals. That power is being routed to a series of chargeable batteries in Coffin"s lab s.p.a.ce. Except Coffin didn"t purchase order the batteries."

"Nnebuogor," Ferron guessed.

"Two points," said Damini. "It"s a stretch, but she could have come in to the office today specifically to see if the cops stopped by."

"She could have ... " Indrapramit said dubiously. "You think she killed him because he found out she was stealing power? For what purpose?"

"I"ll get on her email and media," Damini said. "So here"s my speculation: imagine this utility virus, spreading through the smart grid from aptblock to aptblock. To commit the murder-n.o.body had to be in the room with him, not if his four-dimensional manipulators were within range of him. Right? You"d just override whatever safety protocols there were, and ... boom. Or squish, if you prefer."

Ferron winced. She didn"t. Prefer, that was. "Any sign that the manipulators were interfered with?"

"Memory wiped," Damini said. "Just like the cat. Oh, and the other thing I found out. Dexter Coffin is not our boy"s first ident.i.ty. It"s more like his third, if my linguistic and semantic pa.r.s.ers are right about the web content they"re picking up. I"ve got Conan on it too-" Conan was another of the department"s expert systems "-and I"m going to go over a selection by hand. But it seems like our decedent had reinvented himself whenever he got into professional trouble, which he did a lot. He had unpopular opinions, and he wasn"t shy about sharing them with the net. So he"d make the community too hot to handle and then come back as his own sockpuppet-new look, new address, new handle. Severing all ties to what he was before. I"ve managed to get a real fix on his last ident.i.ty, though-"

Indrapramit leaned forward, folding his arms against the chill. "How do you do that? He works in a specialized-a rarified-field. I"d guess everybody in it knows each other, at least by reputation. Just how much did he change his appearance?"

"Well," Damini said, "he used to look like this. He must have used some rightminding tactics to change elements of his personality, too. Just not the salient ones. A real chameleon, your a.r.s.ehole."

She picked a still image out of the datastream and flung it up. Ferron glanced at Indrapramit, whose rakish eyebrows were climbing up his forehead. An East Asian with long, glossy dark hair, who appeared to stand about six inches taller than Dr. Coffin, floated at the center of her perceptions, smiling benevolently.

"Madam, saab," Damini said. "May I present Dr. Jessica Fang."

"Well," Ferron said, after a pause of moderate length. "That takes a significant investment." She thought of Aristotle: As the condition of the mind alters, so too alters the condition of the body, and likewise, as the condition of the body alters, so too alters the condition of the mind.

Indrapramit said, "He has a taste for evocative handles. Any idea why the vanishing act?"

"I"m working on it," Damini said.

"I"ve got a better idea," said Ferron. "Why don"t we ask Detective Morganti?"

Indrapramit steepled his fingers. "Boss... . "

"I"ll hear it," Ferron said. "It doesn"t matter if it"s crazy."

"We"ve been totally sidetracked by the cat issue. Because Chairman Miaow has to be Niranjana, right? Because a clone would have expressed the genes for those markings differently. But she can"t be Niranjana, because she"s not wiped: she"s factory-new."

"Right," Ferron said cautiously.

"So." Indrapramit was enjoying his dramatic moment. "If a person can have cosmetic surgery, why not a parrot-cat?"

"Chairman Miaow?" Ferron called, as she led Indrapramit into her flat. They needed tea to shake off the early morning chill, and she was beyond caring what the neighbors thought. She needed a clean uniform, too.

"Miaow," said Chairman Miaow, from inside the kitchen cupboard. "Oh, dear." Indrapamit followed Ferron in. Smoke sat demurely in the middle of the floor, tail fluffed over his toes, the picture of innocence. Ferron pulled wide the cabinet door, which already stood ten inches ajar. There was Chairman Miaow, purring, a shredded packet of tunafish spreading dribbles of greasy water across the cupboard floor.

She licked her chops ostentatiously and jumped down to the sink lip, where she balanced as preciously as she had in Coffin"s flat.

"Cat," Ferron said. She thought over the next few things she wanted to say, and remembered that she was speaking to a parrot-cat. "Don"t think you"ve gotten away with anything. The fox is getting the rest of that."

"Fox food is icky," the cat said. "Also, not enough taurine."

"Huh," Ferron said. She looked over at Indrapramit. He looked back. "I guess she"s learning to talk."

They had no problem finding Detective Morganti. The redheaded American woman arrived at Ferron"s aptblock with the first rays of sunlight stroking the vertical farms along its flanks. She had been sitting on the bench beside the door, reading something on her screen, but she looked up and stood as Ferron and Indrapramit exited.

"Sub-Inspector Ferron, I presume? And Constable Indrapramit, how nice to see you again."

Ferron shook her hand. She was even more imposing in person, tall and broad-chested, with the shoulders of a cartoon superhuman. She didn"t squeeze.

Morganti continued, "I understand you"re the detective of record on the Coffin case."

"Walk with us," Ferron said. "There"s a nice French coffee shop on the way to the Metro."

It had shaded awnings and a courtyard, and they were seated and served within minutes. Ferron amused herself by pushing the crumbs of her pastry around on the plate while they talked. Occasionally, she broke a piece off and tucked it into her mouth, washing b.u.t.tery flakes down with thick, cardamom-scented brew.

"So," she said after a few moments, "what did Jessica Fang do in Honolulu? It"s not just the flame wars, I take it. And there"s no warrant for her that we could find."

Morganti"s eyes rose. "Very efficient."

"Thank you." Ferron tipped her head to Indrapramit. "Mostly his work, and that of my archinformist."

Morganti smiled; Indrapramit nodded silently. Then Morganti said, "She is believed to have been responsible for embezzling almost three million ConDollars from her former employer, eleven years ago in the Hawaiian Islands."

"That"d pay for a lot of ident.i.ty-changing."

"Indeed."

"But they can"t prove it."
