When he had finished speaking, Professor McGonagall looked slightly confused.
“Malfoy took something to Borgin and Burkes for repair?”
“No, Professor, he just wanted Borgin to tell him how to mend something, he didn’t have it with him. But that’s not the point, the thing is that he bought something at the same time, and I think it was that necklace—”
“You saw Malfoy leaving the shop with a similar package?”
“No, Professor, he told Borgin to keep it in the shop for him—”
“But Harry,” Hermione interrupted, “Borgin asked him if he wanted to take it with him, and Malfoy said no—”
“Because he didn’t want to touch it, obviously!” said Harry angrily.
“What he actually said was, ‘How would I look carrying that down the street?’” said Hermione.
“Well, he would look a bit of a prat carrying a necklace,” interjected Ron.
“Oh, Ron,” said Hermione despairingly, “it would be all wrapped up, so he wouldn’t have to touch it, and quite easy to hide inside a cloak, so nobody would see it! I think whatever he reserved at Borgin and Burkes was noisy or bulky, something he knew would draw attention to him if he carried it down the street—and in any case,” she pressed on loudly, before Harry could interrupt, “I asked Borgin about the necklace, don’t you remember? When I went in to try and find out what Malfoy had asked him to keep, I saw it there. And Borgin just told me the price, he didn’t say it was already sold or anything—”
“Well, you were being really obvious, he realized what you were up to within about five seconds, of course he wasn’t going to tell you—anyway, Malfoy could’ve sent off for it since—”
“That’s enough!” said Professor McGonagall, as Hermione opened her mouth to retort, looking furious. “Potter, I appreciate you telling me this, but we cannot point the finger of blame at Mr. Malfoy purely because he visited the shop where this necklace might have been purchased. The same is probably true of hundreds of people—”
“—that’s what I said—” muttered Ron.
“—and in any case, we have put stringent security measures in place this year. I do not believe that necklace can possibly have entered this school without our knowledge—”
“But—”
“—and what is more,” said Professor McGonagall, with an air of awful finality, “Mr. Malfoy was not in Hogsmeade today.”
Harry gaped at her, deflating.
“How do you know, Professor?”
“Because he was doing detention with me. He has now failed to complete his Transfiguration homework twice in a row. So, thank you for telling me your suspicions, Potter,” she said as she marched past them, “but I need to go up to the hospital wing now to check on Katie Bell. Good day to you all.”
She held open her office door. They had no choice but to file past her without another word.
