Chapter 3: The Third Floor

The footsteps kept moving. Even distribution. Each step landed on something different underfoot. One moment solid wood, the next a sound like fabric, then tile, then something that shouldn't have been in a hallway at all. The killer walked like someone who already knew what surface each board would make noise on.

Jarrin pressed his back against the left wall. Jazz leaned against the right. Between them, the stove radiated its strange warmth, and the sealed kitchen door held firm on the handle side. Nobody moved. Nobody breathed much. The house was quiet enough that Jarrin could hear the blood in his own ears.

Jazz pulled a playing card from her jacket's inner pocket, a ten of diamonds by the look of the corner she flashed toward him. She slid it under the door. The gap was maybe half an inch. The card passed through with resistance, catching on something just below the threshold, and came back clean when she tugged it free.

"The seal doesn't break," she said. "I can push down on it with my boot and it won't budge."

Jarrin crouched and slid the card against the handle side instead. He pressed his thumb against it. Nothing moved. He tried again with both hands. The door wouldn't shift a millimeter. Whatever had sealed this room wasn't a simple lock, either. It had been built to hold from both directions.

"Someone designed this to keep us in and them out," Jarrin said.

"Or to keep us in period," Jazz replied.

The footsteps stopped.

They both went still. Jazz counted. Three seconds. Five. Seven. The silence felt deliberate, like someone letting the house's ambient noise fill the space between their breathing. Then the footsteps resumed. Slower. Each step carried more weight than the last, as if the killer was deliberately choosing where to place their feet. The pace dropped until it barely qualified as walking. A crawl. A measurement. Someone counting floorboards.

The footsteps stopped again, and this time the pause was shorter. One beat. Two. Then a vibration traveled through the door, faint but unmistakable. Jazz held her hand flat against the wood. The door hummed, a low shiver that ran through the grain like a finger drawn across a wine glass. Not forceful. Just testing. Probing. Checking whether the seal held.

Jarrin looked at Jazz. Jazz looked at the door. Neither of them touched it again.

The seal held. That made sense. If whatever sealed the door was connected to the killer's system, pulling against it would mean pulling against itself. The door was part of the same architecture as the killer's mechanisms. Pushing on one end meant pushing on the other.

Instead of the door shaking harder, the walls began to move.

The compression started slowly. The distance between the stove and the counter shrank by an inch, then two. Jarrin could track it with his eyes, watching the gap close like a camera zooming. The ceiling dropped next. Not suddenly. A steady descent that made the room feel smaller with every passing second. The kitchen folded inward on itself, with every surface inching toward every other surface like something being packed.

Jarrin popped a kinetic bubble against the wall beside the stove.

The impact tore through plaster and studs in a single ragged tear. The force carried through to the other side, blowing the dining room's wall out in a spray of debris. Jarrin grabbed Jazz's arm and pulled her toward the hole. She went with him, stumbling over the threshold just as the ceiling came down behind them, dropping a full foot in the time it took to clear the doorway.

They landed in the dining room on their hands and knees, scraping palms against a table that had clearly been set for dinner at some point. Silverware. Plates. Crystal glasses that didn't break but rattled across the surface like dice. Jarrin got up first. Jazz was already moving, sweeping the table aside with one arm and clearing a path to the center of the room.

Fred was standing in the middle of the dining room with Daphne, Velma, Shaggy, and Scooby. Fred had clearly been waiting. Daphne was against the far wall. Velma had her glasses back on, though nobody remembered giving them back. Shaggy sat on the floor again, looking like he hadn't gotten comfortable anywhere all night. Scooby was at Shaggy's side, and even the dog looked done with everything.

Preston was missing.

"He didn't come back," Fred said before Jarrin could ask. "The man who ran toward the east wing. The werewolf. I watched him go in. Nobody came out after him except the silence."

"Third body?" Jarrin asked.

Fred nodded. "Appeared in the east wing corridor. The same way the second body appeared in the sealed room. Just there. Materialized where none of us looked directly. No sound, no flash, and no mechanism I can see. One moment the corridor was empty. The next, a dead man on the floor."

Jarrin looked at Jazz. Jazz looked at Jarrin. Neither of them said anything about the similarities between a sealed room and a materialized body, or about the fact that a Stand user could do exactly that kind of thing. The theory Fred was about to propose didn't need a Stand explanation. It was a comfortable one, actually. Mechanical. Logical. Safe.

"Here's what I think," Fred said. "This isn't a personal Stand. Everything we've seen so far points to specialized equipment. The walls closing, the rooms rearranging, the sealed chambers, the stored items in bubbles. These are physical mechanisms. Remote-controlled. Maybe a localized field generator of some kind. A device that manipulates space within a defined radius."

Velma adjusted her glasses. "The physics don't support a field generator powerful enough to compress walls like we saw."

"I didn't say the physics were clean," Fred replied. "I said the abilities suggest equipment. A personal Stand would leave biological signatures. Energy signatures. These don't. The effects are too mechanical, too precise. Someone built this house to function as a machine, and the machine is what's killing us."

Jazz folded her arms. She didn't disagree with Fred, which would have been telling. She wasn't buying it either, but neither was she about to argue about the nature of Stands with a group of people who had no framework for the concept. The truth sat in the room like a third piece of furniture nobody had bought: every ability they'd witnessed was perfectly consistent with a Stand user. The walls, the sealed rooms, the materialized bodies, the stored bubbles. All of it fit. The problem was that explaining that would mean revealing their own nature.

"We split up again," Jazz said. "Third floor. Fred, you confirmed the sealed room moved to a new location upstairs."

"I did. Which is why I think we should stay grounded. Stairs mean exposure."

"Someone with a card-based Stand can navigate a sealed room alone," Jazz said. "Poker Face lets me store attack vectors and store spatial concepts. I can trap the room, card it off, and move through it without touching anything dangerous."

"And I cover your back," Jarrin added. "If the walls close, I pop kinetic bubbles through them. If something tries to get close, I steal its distance."

Fred shook his head. "The third floor has already rearranged once. The staircase may not look like stairs when you get there."

The group listened to the staircase above them. A creak. Then another. The steps themselves were moving beneath their feet, the architecture shifting with each person standing on it, as if the house knew they were looking at it.

"We go up," Jarrin said. "All of us, or none of us. One at a time is how you get killed."

Fred stared at him for a long moment. Whatever he wanted to say, he decided against it. He nodded once and stepped toward the stairs.

The staircase was intact when they reached it, though barely. The steps had a faint shimmer across their surface, like the air above hot pavement. Each tread was slightly smaller than the one below it, which made the geometry feel wrong. The third step up was maybe six inches narrower than the first. By the seventh step, the width had compressed enough that walking it required actual focus. Jarrin went first. Jazz followed. Fred took Velma's arm, and they moved up as a group, each person placing their feet with the same careful deliberation that a bomb squad uses when approaching something unexploded.

The stairs compressed beneath them. The ceiling dropped in segments, forcing each person to duck or be hit. Shaggy ducked without thinking. Scooby ducked instinctively, and his ears scraped the falling plaster. Daphne went down on one knee twice. Fred counted the steps. Seven. The count changed when they looked back, and the stairs now read eleven. The staircase was aware of the group on it, that much was obvious. It was adjusting to accommodate the weight of their presence, and the adjustment meant fewer steps and a shorter distance between the floors.

They reached the third floor without further incident. Or rather, without further incident that anyone wanted to discuss. The corridor ahead stretched in a single direction, and at the far end, a door stood open that none of them had placed there.

The door was wood. Dark, like the one Jarrin had found in the west wing, but this one wasn't sealed shut. It was open. Through the doorway, a room. A bed. A body on the bed.

The same choke marks. The same arrangement of bubbles along the walls, pulsing in sync. Belts, glasses, a scarf. Personal effects. Three victims now, all treated the same way. All their belongings collected and suspended in the same breathing bubbles, and the third victim's effects this time included a ring, a phone, and a photograph.

Jazz stepped closer. The photograph sat in its own bubble, floating at shoulder height, pulsing with the others. She didn't need to be close to see what it contained. The image was clear enough through the translucent sphere.

It showed Jarrin and Jazz at the party. Standing near the buffet table. Jazz laughing with her head tilted back, Jarrin holding a drink, both of them caught in a moment of actual ease. The photo had the casual quality of something taken by a stranger, unposed, natural, the kind that only gets captured if someone has been watching.

Except this photo existed in a killer's collection of trophies. A version of events that should not have occurred, already filed away in the killer's system before anyone had reason to worry.

Jarrin pocketed the photograph. He pulled the bubble toward him with his thumb, popped it, and caught the image before it could dissolve. The photograph landed in his hand, real and warm and already slightly creased from handling. The lock marble in his other pocket hummed faintly, a vibration he could feel through his thigh.

"Did you feel that?" Jazz asked.

"Yeah."

"The lock marble responded. It's still warm from the first theft, the tie. And now this." She gestured at the bubbles still floating along the walls. "Everything in those containers. Everything the killer stores. It's connected to whatever he's holding, and if you touched one bubble, you touched them all."

Jarrin looked at the photograph. Jarrin and Jazz at the party. A photo that shouldn't exist, already in the killer's collection, already in his pocket. Every bubble in this room pulsed with the same rhythm. The same frequency. The same system. And he held pieces of it now. The tie. The photograph. Possibly more, if he chose to take more.

The lock marble hummed again, fainter this time, fading. It had given him the concept of a lock once. The photograph was just an object. But the fact that he could reach into the killer's collection and pull things out without anything happening to him meant one of two things. Either the killer had already abandoned these items, or the killer hadn't realized Jarrin was there yet.

The footsteps started again. Coming up the stairs. The wood vibrated beneath their feet with each step, carrying the sound through the floor and up into the third floor corridor. Close. Close enough that Jarrin could count the pauses between them, could track the approach in real time as the killer climbed toward the sound of their breathing.

Jarrin and Jazz stood between the sealed room and the staircase. Third body on the bed between them and the wall. No room to retreat. The killer was three flights up, descending toward them, coming to collect what they had just touched.
