Harry could have passed it as a fluke if he hadn’t learned that Katie’s friend, Leanne, said that the necklace was meant for Dumbledore. Katie suddenly had the package when she had gone to the Three Broomsticks. It was like a light went off in his mind. For a first attempt, he couldn’t say it was bad. The Malfoy Heir was trying at least, even if the attempt was a pitiful one. Though he didn’t say on who he knew was behind it, if Malfoy wanted to get caught, that would be on him. He knew as much that Malfoy didn’t put the curses on that necklace. There were a few options there. It was possible that the necklace was already cursed. There were plenty of them in the Malfoy Manor or someone did it for him. He could see Bellatrix doing that, she loved her curses after all.
