Ralph, I suspect that's Rowling's people, or the publisher.
I've got the book..
Haha, feast yer BOC luvin' eyes on this passage from chapter 2..
>“Were you expecting a package?” Wardle asked.
Robin explained about the disposable wedding cameras.
“What did he do once you’d taken it?”
“Got back on the bike and left. He drove off into Charing Cross Road.”
There was a knock on the door of the flat and Detective Sergeant Ekwensi reappeared holding the note that Strike had noticed lying beneath the leg, which was now enclosed in an evidence bag.
“Forensics are here,” she told Wardle. “This note was in the package. It would be good to know whether it means anything to Miss Ellacott.”
Wardle took the polythene-covered note and scanned it, frowning.
“It’s gibberish,” he said, then read aloud: “‘ A harvest of limbs, of arms and of legs, of necks—’”
“‘— that turn like swans,’” interrupted Strike, who was leaning against the cooker and too far away to
read the note, “‘ as if inclined to gasp or pray.’”
The other three stared at him. “They’re lyrics,” said Strike. Robin did not like the expression on his face. She could tell that the words meant something to him, something bad. With what looked like an effort, he elucidated: “From the last verse of ‘Mistress of the Salmon Salt.’ By Blue Öyster Cult.”
Detective Sergeant Ekwensi raised finely penciled eyebrows. “Who?”
“Big seventies rock band.”
“You know their stuff well, I take it?” asked Wardle.
“I know that song,” said Strike.
“Do you think you know who sent this?”
Strike hesitated. As the other three watched him, a confused series of images and memories passed rapidly through the detective’s mind. A low voice said, She wanted to die. She was the quicklime girl.
