QUOTE : River was in his office, having spent the day staring at his screen, or else through the window, which had planted a square of sunlight onto the vacant desk he shared the room with. It had once been where Sid Baker sat, and that remained its chief significance even during JK Coe’s tenure, which hadn’t been fair on Coe, but Slough House wasn’t big on fairness. And now Sid was back. All this time, she’d been in the world, hidden away; partly erased but still breathing, waiting for the moment to appear to him, in his grandfather’s study. For months he’d been wondering what secrets might be preserved in that room, encrypted among a wealth of facts and fictions. Bringing them into the light would be a task for an archivist—a Molly Doran. He remembered sitting in the kitchen once, watching his grandmother prepare a Christmas goose: this had involved removing its organs, which Rose had set about with the same unhurried calm she had approached most things, explaining as she did so the word haruspicate. To divine the future from the entrails of birds or beasts. He’d planned the opposite: to unshelve those books, crack their spines, break their wings, and examine their innards for clues to the past. His grandfather’s past, he’d assumed. Instead, what he’d found in that room was something broken off from his own life. Now read on.
