Author's Preface
Zack answered on the first ring this time, no hesitation in his voice at all when Cassian said the word Renner.
"I found an address an hour ago," Zack said. "Wasn't going to call you this late, didn't want to scare you more than you already are. But if you're awake—"
"I'm awake." Cassian was already pulling on his shoes, laptop shoved into his bag, his father's obituary still glowing faintly behind his eyes even with the screen closed. "Pick me up round the corner. Not outside the house. I don't want anyone asking questions before I've got answers to give them."
Renner lived twenty minutes away, in a narrow terraced street that looked, in the sodium-orange glow of the streetlights, exactly like every other unremarkable street in the city — the kind of place nobody would ever imagine as the address where a mystery either closed or cracked wide open. Zack parked two doors down and killed the engine, and for a moment neither of them moved, the enormity of what they were about to do settling over the car like something physical.
"If your dad really is—" Zack started, carefully, and didn't finish the sentence, because there wasn't a version of it that didn't sound insane said out loud in a cold car at midnight.
"I know," Cassian said. "Let's just talk to Renner. One thing at a time."
The front door was ajar.
Not wide open — just a few inches, enough for the hallway's darkness to breathe out into the night, enough that both of them stopped dead on the pavement and stared at it with the specific, prickling dread of two people who had already, separately, lived through one version of a night that started exactly this quietly and ended in catastrophe.
"That's not right," Zack murmured. "People don't leave their door open at midnight in this part of town."
Cassian's heart was going hard enough that he could feel it in his ears, but the same cold, ruthless clarity that had carried him through three impossible days pushed him forward anyway, up the short path, toward the gap in the door.
"Mr. Renner?" he called softly, and got nothing back except the low hum of a house that was, he understood with growing certainty, entirely too still.
Zack pushed the door open the rest of the way, and the smell reached them before anything else did — copper and something underneath it, chemical and wrong, a smell Cassian's body recognized even though his mind hadn't caught up yet, some ancient animal part of him already flooding with adrenaline before he'd taken a single step into the hallway.
They found him in the kitchen.
Cassian would spend a long time afterward trying not to remember the specifics — the angle of the body slumped against the cabinets, the overturned chair, the phone lying a few feet away with its screen still faintly, uselessly glowing — but in the moment itself there was no room for anything except a kind of total, roaring silence in his own head, the world narrowing down to one single, unbearable fact.
Renner was dead. Recently dead — the kind of recently that made the back of Cassian's neck crawl, because recently meant tonight, meant maybe hours, meant possibly, horribly, that whoever had done this had walked out of this house not long before two boys who'd woken up dead once already walked into it.
"Don't touch anything," Zack said, voice gone tight and controlled in the specific way of someone forcing calm onto a situation that did not deserve it. "We need to call this in. We need to call it in right now."
"Wait." Cassian's voice came out strange, thin, but he found himself crouching anyway, careful not to touch the body, staring instead at the phone lying near Renner's outstretched hand, its screen still lit with the soft, patient glow of a call log left open. "Look."
The most recent call, timestamped less than two hours ago, sat at the top of the log — no name attached, just a number, the specific absence of a saved contact that told Cassian, with a sick certainty, that whoever had called Renner tonight had done so from a device Renner had never spoken to before, or had deliberately never saved.
Beneath it, though — and this was the thing that made Cassian's whole body go cold — a second entry, three days old, dated Monday, the day before any of this had started. A call, twelve minutes long, from a number that was saved.
Saved under a single word.
Dad.
Cassian stared at it for a long moment that seemed to stretch out and swallow the whole kitchen, the whole house, the whole impossible night, and understood, with a clarity that felt like falling, that the theory he'd built alone on his bedroom floor a few hours ago — fragile, half-formed, built out of a missing death certificate and a vague obituary — had just been handed something close to proof. His father's name, saved in a dead man's phone, twelve minutes of conversation the day before the loop had even begun.
His father was alive. His father had spoken to Renner — to the man who'd arranged the very plane meant to kill his whole family — the day before any of it started.
"Cassian." Zack's voice, urgent now, pulling him back. "We need to go. Now. If whoever did this is still close, if they know we're here—"
They didn't finish the thought. They didn't need to. Cassian rose on unsteady legs, forced himself to memorize the number glowing on that screen before the world made him leave it behind, and let Zack pull him back out into the cold night air, back to the car, back onto the ordinary sleeping street where nothing outside that house gave any hint at all of what had just happened inside it.
They didn't call the police. Not yet — Zack argued, quietly, urgently, that a fourteen-year-old and a stranger discovered at the scene of a murder mere hours before a flight neither of them could explain their certainty about would create exactly the kind of chaos that might get them both detained, questioned, separated, unable to stop anything at all before morning came. It felt wrong, leaving a dead man behind them in a dark kitchen. It felt, Cassian thought, sitting rigid in the passenger seat as the streetlights slid past, like exactly the kind of choice that would haunt him regardless of how this ended.
"This shouldn't be possible," Zack said quietly, hands tight on the wheel, eyes fixed on the road. "Renner wasn't on that plane. He wasn't part of what either of us remembers happening. If we're stuck reliving three fixed days, heading toward one fixed outcome — how does a man who was never part of the crash end up murdered, tonight, in a version of events that's supposed to already be written?"
Cassian sat with the question, feeling it settle into the same cold, clear space where every other impossible thing this week had eventually found room to fit.
"Because it's not fixed," he said slowly, working it out even as he said it. "Whoever's doing this — whoever's actually driving all of it — isn't just replaying a script waiting for us to catch up. They're still moving. Still reacting. Renner's dead tonight because someone decided, in real time, that he'd become a liability. Which means someone out there already knows we're looking. Already knows we're getting close."
"Which means the loop isn't protecting us," Zack said quietly. "It's not some safety net where nothing we do really counts until we hit the plane again. Every hour between now and tomorrow's flight, things can still change. People can still die who weren't supposed to. And if that's true—"
"Then anyone can die," Cassian finished, ice moving through his chest. "Not just the people who died the first time. Anyone who gets too close, from now until we're back on that plane, is in danger. Real danger. Not a memory of danger — actual, first-time, never-happened-before danger."
Neither of them said anything else for a long moment, the car rolling through empty streets toward a house full of people who had no idea how much closer this had all just come to unraveling around them.
"Your dad," Zack said finally, carefully. "If he's alive — if he called Renner the day before this started — then he's not a victim in this, Cassian. He's part of it. Whatever's happening, whatever this actually is, your father is connected to it in a way none of us have understood yet."
Cassian stared out the window at the dark, sleeping city, and thought about a closed casket, a rushed burial, a mother's gentle insistence that he didn't need to see the body, a month of grief built on a story nobody had ever actually verified — and felt something in him that had been quietly, desperately hoping his father was simply, uncomplicatedly gone finally give way to something far more frightening.
Not grief anymore. Something closer to dread.
"Then I need to find him," he said quietly, "before the plane leaves tomorrow. Because I don't think he's the person who's been protecting this family from whatever's coming."
He looked at Zack, and Zack looked back, and neither of them said the rest of it out loud, because it didn't need saying. They were both thinking the same unbearable thought, sitting in a dark car two streets from a dead man's house, with less than sixteen hours left before the sound they both still heard in their sleep came due all over again.
What if he's the one making sure it does.
