Isaac felt him from forty feet out.
Not a sound. Not a shape. Just a change in the air pressing against the edge of the awareness Cipher kept running at all times now — a bubble that didn't have a name yet because Isaac hadn't decided he wanted one, radiating out from him in every direction, cataloguing every heartbeat that crossed into it.
Forty feet was new. A month ago it had been ten. He didn't know if that meant Cipher was getting stronger or he was just finally paying attention.
*He's alone,* Cipher said, from the dark window glass across the room. *Which is either very stupid or very confident. Guess which one I'm hoping for.*
"Neither," Isaac said. "He's calculated."
*Boring answer. I liked stupid better.*
Isaac crossed the room without hurrying. Echo was asleep on the couch with Wren's coat draped over her, one hand still curled around the mug of tea she hadn't finished. Wren sat by the window, perfectly still, eyes open, already watching the door before Isaac reached it — she'd felt it too, in whatever way she felt things now.
"Someone's coming," she said. Not a question.
"I know."
He got to the door two seconds before the knock landed, and opened it before Cael Calder's hand finished the motion.
Cael didn't flinch. That told Isaac something on its own — a man expecting to knock on a closed door didn't smile that fast at an open one. He'd known Isaac would feel him coming. Or he hadn't cared either way, which was its own kind of information
"Evening," Cael said.
"You're not supposed to know this address."
"I'm not supposed to know a lot of things." Cael's hands stayed visible, loose at his sides, no weapon, nothing that read as a threat. "I know them anyway. Comes with the job."
"Which job. The one Lucien thinks you have, or the one you actually have."
Something in Cael's face didn't move, which was its own kind of confirmation. He'd been waiting to find out if Isaac would say it plainly. Now he knew.
"How long," Cael asked.
"Since the third week. You ask questions soldiers don't ask. You remember answers too well for someone who's supposedly bad at paperwork." Isaac didn't blink. "Lucien knows too. He's known longer than I have."
"And neither of you said anything."
"You weren't hurting anyone. Watching costs nothing if you don't act on it." Isaac's voice didn't change register. "You're here. That means you're about to start costing something."
Cael exhaled — not quite a laugh — and reached into his jacket slowly, telegraphing every inch of the motion, and held out a folded document.
"Three Crown Cult gathering points. Solen's operational pattern. Enough to move on her before she reorganizes from Crestward Lane." He hadn't let go of it yet. "I've had this for four days."
"Why bring it here instead of filing it."
"Because filing it puts it through the council member first, and the council member decides what Unit Seven gets told and when. You'd get it eventually. Eventually isn't fast enough for a Crownbearer who just lost a safehouse and knows she's being hunted."
"That's not an answer. That's a justification." Isaac finally took the document. "Why do you care if it's fast enough."
Cael was quiet for a moment — the first honest silence Isaac had heard from him in three years.
"Because I've been watching you build something in that apartment for two weeks," he said, "and I'd like to see what it turns into before somebody's incompetence gets it killed."
Behind Isaac, Wren hadn't moved. Echo hadn't woken. The room held the specific stillness of people pretending to be asleep who weren't.
Isaac unfolded the document one-handed and scanned it once — locations, timestamps, a name underlined twice. Real intelligence. Expensive intelligence, the kind that cost something to get and more to hand over.
"This makes you a liability to whoever you actually report to," Isaac said.
"Only if they find out I gave it to you instead of them."
"They will."
"Probably." Cael's smile didn't waver, but something under it did — a flicker of the calculation Isaac had clocked in him from the start, running numbers that had just gotten worse. "I was hoping we could discuss what happens to me if that math goes badly before it actually does."
Isaac looked at him for a long moment. Then stepped back from the doorway, just far enough to leave room.
"Come in," he said. "You're already inside my radius. Might as well stop pretending you're not."
