Shortly before her disappearance, Margot Bamborough booked herself into the Bride Street Nursing Home in Islington, a private facility which in 1974 provided discreet abortions.

The Bride Street Nursing Home closed its doors in 1978 and no records exist to show whether Bamborough had the procedure. However, the possibility that she allowed a friend to use her name is mooted by the author of Whatever Happened to Margot Bamborough?, who notes that the Irish woman and fellow Bunny Girl Bamborough was supposedly meeting in the pub that night might have had good reason for maintaining the pub story, even after Bamborough’s death.

Bride Street Nursing Home lay a mere eight minutes’ walk from Dennis Creed’s basement flat on Liverpool Road. The possibility remains, therefore, that Margot Bamborough never intended to go to the pub that night, that she told the lie to protect herself, or another woman, and that she may have been abducted, not from a street in Clerkenwell, but a short distance from Creed’s house near Paradise Park.

“What the—?” began Strike, looking thunderstruck. “My copy hasn’t got this bit. You’ve got an extra three paragraphs!”

“I thought you hadn’t read it,” said Robin, sounding satisfied. “Yours can’t be a first edition. Mine is. Look here,” she said, flicking to a place at the back of the book, while Strike still held it. “See there, the endnote? ‘Whatever Happened to Margot Bamborough? by C. B. Oakden, published 1985.’ Except it wasn’t published,” said Robin. “It was pulped. The author of this,” she said, tapping The Demon of Paradise Park, “must’ve got hold of an advance copy. I’ve been digging,” Robin went on. “All this happened pre-internet, obviously, but I found a couple of mentions of it online, in legal articles about suing for libel to stop publication.

“Basically, Roy Phipps and Oonagh Kennedy brought a joint action against C. B. Oakden and won. Oakden’s book was pulped and there was a hasty reprint of The Demon of Paradise Park, without the offending passage.”

“C. B. Oakden?” repeated Strike. “Is he—?”

“Dorothy-the-practice-secretary’s son. Exactly. Full name: Carl Brice Oakden. The last address I’ve got for him was in Walthamstow, but he’s moved and I haven’t managed to track him down yet.”

Strike re-read the paragraphs relating to the abortion clinic, then said,

“Well, if Phipps and Kennedy succeeded in suing to stop publication, they must have convinced a judge that this was partly or completely false.”

“Horrible thing to lie about, isn’t it?” said Robin. “Bad enough if he was saying Margot had the abortion, but hinting that Oonagh had it, and was covering up where Margot was that night—”

“I’m surprised he got it past lawyers,” said Strike.

“Oakden’s publisher was a small press,” said Robin. “I looked them up, too. They went out of business not long after he had his book pulped. Maybe they didn’t bother with lawyers.”

“More fool them,” said Strike, “but unless they had some kind of death wish, this can’t have been entirely invented. He must’ve had something to base it on. And this bloke,” he held up The Demon of Paradise Park, “was a proper investigative journalist. He wouldn’t have theorized without seeing some proof.”

“Can we check with him, or is he—?”

“Dead,” said Strike, who sat for a moment, thinking, then went on:

“The appointment must’ve been made in Margot’s name. The question is whether she had the procedure, or whether somebody used her name without her knowing.” Strike re-read the first few lines of the passage. “And the date of the appointment isn’t given, either. ‘Shortly before her disappearance’… weasel words. If the appointment had been made for the day she disappeared, the author would say so. That’d be a major revelation and it’d have been investigated by the police. ‘Shortly before her disappearance’ is open to wide interpretation.”

“Coincidence, though, isn’t it?” said Robin. “Her making an appointment so close to Creed’s house?”

“Yeah,” said Strike, but after a moment’s consideration he said, “I don’t know. Is it? How many abortion clinics were there in London in 1974?”

Handing the book back to Robin, he continued,

“This might explain why Roy Phipps was jumpy about his daughter talking to Oonagh Kennedy. He didn’t want her telling his teenage daughter her mother might’ve aborted her sibling.”

“I thought of that, too,” said Robin. “It’d be an awful thing to hear. Especially when she’s lived most of her life wondering whether her mother ran out on her.”

“We should try and get hold of a copy of Whatever Happened to Margot Bamborough?” said Strike. “There might still be copies in existence if they got as far as printing them. He could’ve given some away. Review copies and the like.”

“I’m already on it,” said Robin. “I’ve emailed a few different second-hand book places.”

This wasn’t the first time she had found herself doing something for the agency that made her feel grubby.

“Carl Oakden was only fourteen when Margot disappeared,” she continued. “Writing a book about her, milking the connection, claiming Margot and his mother were close friends—”

“Yeah, he sounds a common-or-garden shit,” Strike agreed. “When did he leave his address in Walthamstow?”

“Five years ago.”

“Had a look on social media?”

“Yes. Can’t find him.”

Strike’s mobile vibrated in his pocket. Robin thought she saw a flicker of panic in his face as he fumbled to find it, and knew that he was thinking of Joan.

“Everything all right?” she asked, watching his expression darken as he looked down at his mobile screen.

Strike had just seen:

Bruv, can we please talk this over face to face? The launch and the new album are a big deal for Dad. All we’re asking—

“Yeah, fine,” he said, stuffing the phone back in his pocket, the rest of the message unread. “So, you wanted to go to—?”

For a moment, he couldn’t remember the unlikely place Robin had told him she wanted to visit, and which was the reason they were currently sitting in this particular café.

“The National Portrait Gallery,” she said. “Three of Postcard’s postcards were bought in their gift shop.”

“Three of—sorry, what?”

He was distracted by what he’d just read. He’d been quite clear with his half-brother that he had no wish either to attend the party celebrating his father’s new album, or to feature in the photograph with his half-siblings which was to be their congratulatory gift to him.

“Postcard’s postcards—the person who’s persecuting our weatherman,” she reminded him, before mumbling, “it doesn’t matter, it was just an idea I had.”

“Which was?”

“Well, the last-but-one picture Postcard sent was of a portrait they said ‘always reminded’ them of our weatherman. So I thought… maybe they see that painting a lot. Maybe they work at the gallery. Maybe they secretly want him to know that, to come looking for them?”

Even as she said it, she thought the theory sounded far-fetched, but the truth was that they had absolutely no leads on Postcard. He or she had failed to turn up at the weatherman’s house since they’d been watching it. Three postcards bought in a single place might mean something, or perhaps nothing at all. What else did they have?

Strike grunted. Unsure whether this indicated a lack of enthusiasm for her theory about Postcard, Robin returned her copy of The Demon of Paradise Park to her handbag and said,

“Heading for the office after this?”

“Yeah. I told Barclay I’ll take over watching Twinkletoes at two.” Strike yawned. “Might try and get a couple of hours’ kip first.”

He pushed himself into a standing position.

“I’ll call you and let you know how I get on with Gregory Talbot. And thanks for holding the fort while I was away. Really appreciate it.”

“No problem,” said Robin.

Strike hoisted his kit bag onto his shoulder and limped out of the café. With a slight feeling of anti-climax, Robin watched him pause outside the window to light a cigarette, then walk out of sight. Checking her watch, Robin saw that there was still an hour and a half before the National Portrait Gallery opened.

There were doubtless more pleasurable ways of whiling away that time than in wondering whether the text that Strike had just received had come from Charlotte Campbell, but that was the distraction that occurred to Robin, and it occupied her for a surprising proportion of the time she had left to kill.
