The first location Draco checked was Grimmauld Place. He saw signs that Harry had been there, but nothing that showed he was staying. It took him two tries to apparate to their tree, and he faced the same result. It was well after 3:30 now, and Draco was out of ideas. It was only after going back to Grimmauld Place did he so obviously remember where Harry would be. Draco hoped so, because that meant that he had a chance to repair things.
