one-story buildings, a dozen at the most, unpainted, a patchwork of colors coming from the cast-off wood and scrap particle board that had been given to the residents by the resettlement commission. As far as planned communities went, it didn’t show much planning—just a main street, structures on either side of it, and a few outbuildings that had been thrown up later, possibly by latecomers who preferred a bit of space between themselves and their neighbors.
The first odd thing they saw, about fifty yards outside of town, was a suitcase. It sat in the middle of the road, packed and closed and waiting patiently, as if expecting a ride to the airport. There was no one and nothing else around it.
They looked at one another, then went to it. They stood around the suitcase, staring at it as if expecting it to reveal its history and intentions. It did not.
Trini moved on, holding the gun in front of her.
They reached the first building, and as they came around the front of it, they saw this one had only three walls, not four, built that way on purpose for maximum airflow in the intensely arid environment. They paused and looked inside, the way you’d look into a doll-house. There were cutaway areas: a kitchen, a bedroom, a bathroom (that room had a door), and another tiny bedroom at the far end of the structure. In the kitchen, there was food on the table, buzzing with flies. But there were no people.
Roberto looked around. “Where is everybody?”
That was the question.
Trini backed away, into the street again, turning in cautious semicircles, scanning the place.
“Cars are still here.”
They followed her gaze. There were cars, all right, just about one per driveway, a jeep or motorcycle or pickup or old sedan. However the residents had managed to get where they were going, they hadn’t driven.
They continued on, past what might have been a playground, more or less in the center of town. An old metal swing creaked on its chain, blowing in the wind that now swept the desert sand and dust into town ahead of it. Roberto turned and squinted into the coming clouds. The sand ticked against the glass of his faceplate, and it was hard not to blink, though of course he didn’t need to.
Another thirty yards and they reached the other side of town. The front door to the biggest house was ajar, and Trini pushed it open the rest of the way, using the barrel of the Sig Sauer. Roberto gestured to Hero to wait on the porch, and he and Trini stepped inside, one after the other, in a practiced maneuver.
Hero waited in front, watching their movements through the open door and the dirty front window. They searched the place, room by room, Trini always in the lead, gun in hand. Roberto was the more thorough and perhaps the more cautious of the two, moving carefully and steadily and never facing in the same direction for too long. Hero admired the grace and ease with which he moved, even in the cumbersome suit. But she also knew there was nothing to fear in there. Everything about Kiwirrkurra so far suggested a ghost town—she was sure of their result before Trini came out a few minutes later and announced it.
“Fourteen houses, twelve vehicles, zero residents.”
Roberto put his hands on his hips, relaxing his guard a bit. “What the actual fuck?”
That was when Hero saw what they’d come for. There, at the far end of town, in front of one of the best kept of the very modest houses, was a silver metal tank, its finish recently polished to a bright and reflective shine.
“I don’t think that’s from here.”
They walked toward the tank, wary. The wind swirled harder, and the dust in the air billowed around the houses, rearing up in columns in front of them before dust-deviling back to the ground in a corkscrew and moving on. It was getting hard to see.
“Stop here.” Hero held a hand out when they were still ten feet from the tank. She scanned the ground around them as best she could in the billowing sand, then continued on, searching the ground carefully before she placed each step.
“Walk in my footsteps.”
They did, following her in single file, careful to place their feet directly onto her boot prints as they went.
Hero reached the tank and squatted down. She saw the fungal covering immediately, but only because of her practiced eye. An untrained observer wouldn’t have perceived anything more than a greenish patch on the rounded surface of the tank, a bit like oxidized copper. The tank wasn’t in pristine condition anyway; it had made an uncontrolled re-entry into Earth’s atmosphere, after all, that’s going to put a few dents in anything. But to Hero, the unremarkable greenish patch read like a semaphore.
Trini looked around them, still with her gun at the ready, just in case. She took a few steps toward the house, watching where she walked. She stopped, studying the building, which wasn’t very different from the other ones. But there was one thing she noticed—the car. An old Dodge Dart, it was parked at an odd angle to the house, its hood pushed almost right up against a porch pillar. The porch had a low-slung, corrugated roof that bent down at an angle, and from where the car was parked it wasn’t a very big step up from the hood to the roof. Trini looked up, thinking.
Back at the silver tank, Hero bent down, pulling her sample case around in front of her. She clicked it open, snapped out a 20x magnifying lens, and squeezed it to activate the LED lights around the edge of the beveled glass. Through the lens, she got a closer look at the fungus. It was alive, all right, and florid, visibly seething even at this magnification. She leaned as close as she dared, looking for active fragmentation. There was movement there, and she wished like hell she had a more powerful magnifier, but twenty power was the most the field kit carried, which meant she had to get closer still.
She looked back, over her shoulder, at Roberto.
“Slide your hand through the loop in the suit between my shoulder blades.”
Roberto looked down. There was a tight vertical flap of fabric sewn into the back of the suit, a handle of sorts, with just enough space to get his fingers through. He did as she asked.
“Now hold on tight,” she said. “I’ll pull against you, but don’t let me go. If I start to fall, give me a hard pull back. Don’t be shy about it. Don’t let me touch it.”
“You got it.”
He held on tight. Hero braced her feet just short of the tank, about a foot away from it, and leaned forward, putting the magnifying glass and her mask as close to the surface of the middle of the tank as she possibly could. Roberto hadn’t expected her to have quite as much confidence in him as she apparently did, and he swayed a little as she let her weight fall forward. But he was strong and recovered quickly, resetting his feet and holding her steady.
The faceplate of Hero’s helmet moved to within three inches of the surface of the tank, she switched the lens to max magnification and close focus and flicked the LEDs to their brightest setting.
She gasped. Through the lens, even at this minimal magnification, she could clearly see fruiting bodies sprouting off the mycelium, stalks with a capsule at the top, swelling at their seams with ready-to-spread spores. The mycelium’s growth was so fast it was visible.
“Jesus Christ.”
Roberto couldn’t see around her bulky suit, and the curiosity was killing him. “What is it?”
Hero couldn’t tear her eyes away.
“I don’t know, but it’s huge, and it’s fast. And heterotrophic; it’s got to be pulling carbon and energy out of everything it touches, otherwise there’s no way it …” She trailed off, staring at something intently.
“No way what?”
Hero didn’t answer. She was fascinated by one of the fruiting bodies. Its capsule was bloating beneath the lens, ballooning up off the surface of the tank.
“This is the most aggressive sporing rate I’ve ever—”
With a sharp pop, the entire fruiting body burst, and the
