Denise's flat was the kind of place that had accumulated thirty years of living — every surface a small archaeology of someone's whole self. Postcards from holidays she'd told Ro about in detail. A row of succulents on the windowsill, each one named. The smell of whatever she'd been baking, even now, even standing in the doorway at half past midnight looking at the broken lock.
Ro's hand was still on her phone.
She hadn't called Caelan yet. She'd called 999 first, then stood in the hallway listening to her own heartbeat.
The police had come and gone in forty-five minutes. No one hurt. Some things missing — Denise's external hard drive, a leather journal she'd had for twenty years, a brass compass that had belonged to her grandmother. The kind of things you'd take if you knew what you were looking for and it wasn't anything obvious.
"It is not a burglary," Caelan said, when she finally called.
"I know it's not a burglary."
"I will be there in ten minutes."
She stood in Denise's hallway and looked at the succulents on the windowsill. Every one still there. Twelve little pots. Denise had named them after Pre-Raphaelite painters, which Ro had thought was deeply funny the first time she'd heard it. Millais. Hunt. Rossetti. Burne-Jones. All twelve present, and the compass that had come from Denise's grandmother was gone.
That was the thing about the cult. They were precise.

Denise was staying at her sister's. Ro had called her from outside the flat, standing on the pavement with the September chill coming off the Thames two streets away, and Denise had said *I'm fine, love, stop worrying* in the voice of someone who was not even slightly fine.
They'd met on Ro's first shift at the Hollow Crown, three years ago. Denise had been working there for eleven. She'd taught Ro how to handle the night crowd, which regulars were harmless and which ones needed watching, how to make the coffee the way they liked it without asking. She was fifty-three and divorced and had strong opinions about biscuits and had once told Ro, very seriously, that Ro reminded her of a painting she'd seen at the National Gallery — *a woman in a window, always looking out, never looking back.*
The compass had belonged to Denise's grandmother. A woman who'd come to London in 1962 from Kingston. It was brass and had a crack in the casing that Denise had always said she'd get repaired and never had.
It was gone because of Ro.
She was not going to let herself not acknowledge that.

Caelan arrived in nine minutes. He came through the front door — she'd left it open — and stood in the hallway doing the thing she'd seen him do in the diner when something was wrong. Completely still. Listening to something she couldn't hear.
"They were here within the last three hours," he said.
"The police put it between nine and midnight. She came home from her sister's at nine, found it like this."
"She was not hurt."
"No. She wasn't home." Ro crossed her arms. "They knew she wouldn't be home."
"Yes."
"They knew enough about Denise to know her schedule."
"Yes."
She looked at the succulents. Millais. Hunt. Rossetti. The thin sodium light from the street coming through the window, falling across all twelve of them, casting small shadows.
"The compass," she said. "The journal. The hard drive. What are they looking for?"
"Connections." He was moving through the flat now, careful, not touching anything. "They have been tracking the anchor connection from the outside. They do not have full information about what an anchor is — our information on that is itself incomplete — but they are building a picture. If they can map your relationships, your history, the people you are close to—" He paused at Denise's bookshelf. Tilted his head. "They want to understand your vulnerabilities."
"My vulnerabilities." Flat.
"The people you would do something reckless to protect."
She was quiet for a moment.
"Denise is fifty-three years old," Ro said. "She names her succulents after Pre-Raphaelite painters. She's never hurt anyone in her life."
"I know."
"She got dragged into this because she happens to be kind to me on night shifts."
"Rowan—"
"Don't." Her voice came out harder than she meant. She pulled it back. "I know. I know it's not your fault either. I know you've been trying to contain this." She pressed her fingertips against her eyes. "What do they gain from the compass? A piece of brass with a crack in it that hasn't worked properly since 1974?"
"It is not about the compass. It is about what it represents — an object with personal resonance, carried close, passed through generations. An object a person would grieve." He met her eyes. "They are learning how to hurt you. Specifically."
The succulents. The crack in the compass casing. Denise's voice on the phone saying *I'm fine, love, stop worrying.*
Ro put her back against the wall and slid down it until she was sitting on the floor of Denise's hallway. Just for a second. Just while she recalibrated.
Caelan crouched down, across from her. It was such an un-Caelan thing to do — he was usually so careful about maintaining his particular vertical dignity — that she looked at him.
"I am sorry," he said. And he meant it. She could see that he meant it. "I have been trying to keep this contained. I have not succeeded as well as I should have."
"You've been fighting a three-hundred-year-old cult with better intelligence than you." She pulled her knees up. "It's not a you problem."
"It is becoming a you problem."
"Yeah." She looked at the ceiling. Old plaster, hairline crack running from the light fitting toward the door. "It is."
Silence. Outside, a fox went past on the pavement — she could hear its claws. London's other night shift.
"The Assembly is in three days," she said.
"Yes."
"We still go."
"Rowan—"
"We still go." She looked at him. "Because whatever they took from Denise's flat, they took it to use against us at the Assembly or before it. Right? This is accelerating because of the Assembly. They're rattled that you're going to present formally, that the courts are going to take this seriously."
He was quiet for a moment. Working through it.
"That is a reasonable inference," he said.
"So we don't give them time to use it. We go in three days, we present before they can move again, and we make the courts understand what they're actually dealing with." She stood up, brushing plaster dust off her jeans. "But first."
"First?"
"First we make sure Denise has somewhere safe to stay and she knows not to come back here until this is over." She pulled out her phone. "And then you're going to tell me everything you know about how this cult operates. Not the summary. Not the version you thought I could handle. Everything."
He stood as well. Unfolded himself from the crouch in that way he had, all angles and too-long limbs.
"That conversation will take most of the night," he said.
"I've got nowhere to be until Thursday." She pocketed her phone and looked at him steadily. "They went after someone I care about, Caelan. I'm not going into that Assembly room informed halfway. I need the whole picture."
"You may not like the whole picture."
"I didn't like the partial picture either. At least with the whole one I can make actual decisions." She moved toward the door, paused. "One more thing."
"Yes."
"After this — after the Assembly, after we've dealt with the cult — someone needs to find out how they knew Denise's schedule. That's not intelligence gathering. That's surveillance. And I want to know how far back it goes."
He was quiet for a moment.
"I will find out," he said.
She believed him. That was the thing about Caelan — he said very few things he didn't mean, and the things he meant, he followed through on with the particular patience of someone who had three hundred years and a very long memory.
She walked out of Denise's flat and down the stairs and out into the September street, and she didn't let herself feel what she was feeling until she was three blocks away and alone.
The compass. The journal. Twenty years of someone's private thoughts, taken because that person had been kind to Ro.
She pressed her palms against a brick wall and breathed.
Then she took out her phone and called Denise's number.
"Hello love," Denise said.
"Hey." Ro kept her voice steady. "I need to ask you something."
"Ask."
"Can you stay at your sister's for a bit longer? Maybe a week. Maybe two." Ro closed her eyes. "I'll explain properly when I can. But right now I just need you to not be at your flat."
A pause. Denise, who was sharp as a tack and had been for fifty-three years, said: "Does this have to do with that fella who comes into the diner?"
Ro's eyes opened.
"What fella?"
"The one with the strange eyes. Been coming in since August." A pause. "I've seen the way he looks at you when you're not watching, love. And I've seen the way you don't look at him for exactly the same reason." Another pause. "I'll stay at my sister's."
She hung up before Ro could say anything else.
Ro stood on the September pavement and looked at the sky — London orange, London amber, London never quite dark.
Caelan came up beside her.
"She will be safe at her sister's?" he asked.
"Yeah." Ro started walking. "Come on. You said this conversation would take most of the night. Let's not waste any of it."
He fell into step beside her without another word.
Behind them, somewhere in Denise's flat, twelve succulents named after Pre-Raphaelite painters sat in a row on the windowsill, undisturbed.
Small mercies. Ro was learning to catalogue those too.
But it didn't make the compass any less gone.
And it didn't make three days feel like anywhere near enough time.
