He kept trying to foster a closer relationship with her, which she was attempting to discourage. Only the previous day he had interrupted her as she hovered outside Geraint and Aamir’s door, listening with all her might to a conversation that Aamir was having on the phone about an “inquiry.” From the scant details that Robin had so far heard, she was convinced that the Level Playing Field was under discussion.

“But this isn’t a statutory inquiry?” Aamir was asking, sounding worried. “It isn’t official? I thought this was just a routine… but Mr. Winn understood that his letter to the fundraising regulator had answered all their concerns.”

Robin could not pass up the opportunity to listen, but knew her situation to be perilous. What she had not expected was to be surprised by Raphael rather than Winn.

“What are you doing, skulking there?” he had asked, laughing.

Robin walked hastily away, but she heard Aamir’s door slam behind her and suspected that he, at least, would make sure that it was closed in future.

“Are you always this jumpy, or is it just me?” Raphael had asked, hurrying after her. “Come for a coffee, come on, I’m so bloody bored.”

Robin had declined brusquely, but even as she pretended to be busy again, she had to admit that part of her—a tiny part—was flattered by his attentions.

There was a knock on the door and, to Robin’s surprise, Aamir Mallik entered the room, holding a list of names. Nervous but determined, he addressed Izzy.

“Yeah, uh, hi. Geraint would like to add the Level Playing Field trustees to the Paralympian reception on the twelfth of July,” he said.

“I’ve got nothing to do with that reception,” snapped Izzy. “DCMS are organizing it, not me. Why,” she erupted, wiping her sweaty fringe off her forehead, “does everyone come to me?”

“Geraint needs them to come,” said Aamir. The list of names quivered in his hand.

Robin wondered whether she dared creep into Aamir’s empty office right now and swap the listening devices. She got to her feet quietly, trying not to draw attention to herself.

“Why doesn’t he ask Della?” asked Izzy.

“Della’s busy. It’s only eight people,” said Aamir. “He really needs—”

“‘Hear the word of Lachesis, the daughter of Necessity!’”

The Minister for Culture’s booming tones preceded him into the room. Chiswell stood in the doorway, wearing a crumpled suit and blocking Robin’s exit. She sat down quietly again. Aamir, or so it seemed to Robin, braced himself.

“Know who Lachesis was, Mr. Mallik?” asked Chiswell.

“Can’t say I do,” said Aamir.

“No? Didn’t study the Greeks in your Harringay Comprehensive? You seem to have time on your hands, Raff. Teach Mr. Mallik about Lachesis.”

“I don’t know, either,” said Raphael, peering up at his father through his thick, dark lashes.

“Playing stupid, eh? Lachesis,” said Chiswell, “was one of the Fates. She measured out each man’s allotted lifespan. Knew when everyone’s number would be up. Not a fan of Plato, Mr. Mallik? Catullus more up your street, I expect. He produced some fine poetry about men of your habits. Pedicabo ego vos et irrumabo, Aurelia pathice et cinaede Furi, eh? Poem 16, look it up, you’ll enjoy it.”

Raphael and Izzy were both staring at their father. Aamir stood for a few seconds as though he had forgotten what he had come for, then stalked out of the room.

“A little Classics education for everyone,” said Chiswell, turning to watch him go with what appeared to be malicious satisfaction. “We are never too old to learn, eh, Raff?”

Robin’s mobile vibrated on her desk. Strike had texted. They had agreed not to contact each other during working hours unless it was urgent. She slid the phone into her bag.

“Where’s my signing pile?” Chiswell asked Izzy. “Have you finished that letter for Brenda Bloody Bailey?”

“Printing it now,” said Izzy.

While Chiswell scribbled his signature on a stack of letters, breathing like a bulldog in the otherwise quiet room, Robin muttered something about needing to get going, and hurried out into the corridor.

Wanting to read Strike’s text without fear of interruption, she followed a wooden sign to the crypt, hastened down the narrow stone staircase indicated and found, at the bottom, a deserted chapel.

The crypt was decorated like a medieval jewel casket, every inch of gold wall embellished with motifs and symbols, heraldic and religious. There were jewel-bright saints’ pictures above the altar and the sky-blue organ pipes were wrapped in gold ribbon and scarlet fleurs-de-lys. Robin hurried into a red velvet pew and opened Strike’s text.

Need a favor. Barclay’s done a 10-day stretch on Jimmy Knight, but he’s just found out his wife’s got to work over the weekend & he can’t get anyone else to look after the baby. Andy leaves for a week in Alicante with the family tonight. I can’t tail Jimmy, he knows me. CORE are joining an anti-missile march tomorrow. Starts at 2, in Bow. Can you do it?

Robin contemplated the message for several seconds, then let out a groan that echoed around the crypt.

It was the first time in over a year that Strike had asked her to work extra hours at such short notice, but this was her anniversary weekend. The pricey hotel was booked, the bags packed and ready in the car. She was supposed to be meeting Matthew after work in a couple of hours. They were to drive straight to Le Manoir aux Quat’Saisons. Matthew would be furious if she said she couldn’t go.

In the gilded hush of the crypt, the words Strike had said to her when he had agreed to give her detective training came back to her.

I need someone who can work long hours, weekends… you’ve got a lot of aptitude for the job, but you’re getting married to someone who hates you doing it…

And she had told him that it didn’t matter what Matthew thought, that it was up to her what she did.

Where did her allegiance lie now? She had said that she would stay in the marriage, promised to give it a chance. Strike had had many hours of unpaid overtime out of her. He could not claim that she was workshy.

Slowly, deleting words, replacing them, overthinking every syllable, she typed out a response.

I’m really sorry, but it’s my anniversary weekend. We’ve got a hotel booked, leaving this evening.

She wanted to write more, but what was there to say? “My marriage isn’t going well, so it’s important I celebrate it”? “I’d much rather disguise myself as a protestor and stalk Jimmy Knight”? She pressed “send.”

Sitting waiting for his response, feeling as though she were about to get the results of medical tests, Robin’s eyes followed the course of twisting vines that covered the ceiling. Strange faces peered down at her out of the molding, like the wild Green Man of myth. Heraldic and pagan imagery mingled with angels and crosses. It was more than a place of God, this chapel. It harked back to an age of superstition, magic and feudal power.

The minutes slid by and still Strike hadn’t answered. Robin got up and walked around the chapel. At the very back she found a cupboard. Opening it, she saw a plaque to suffragette Emily Davison. Apparently, she had slept there overnight so that she could give her place of residence as the House of Commons on the census of 1911, seven years before women were given the vote. Emily Davison, she could not help but feel, would not have approved of Robin’s choice to place a failing marriage above freedom to work.
