Lucius looked up at him silently as he turned to sort through the ordered clutter behind him. When he saw it gleaming out at him, he felt absurdly gratified. Victories were coming scarce, and any sort of success - even if it had grown out of a disastrous home-invasion - lifted his spirits a little. He stood to accept the box from him when it was offered, flipped it over once, carefully, in his hand, and then slipped it into his robes.
"The complaint department, yes - I believe I know where that is," he said, without a trace of irony. Lucius had had a habit, not so long ago, of inundating various institutions with angry letters. It was a pastime he rather missed. Not enough to stop in for old times' sake, of course. Not today. "Good day to you, then." He turned to the door. "I'm sure one of your sticky-fingered aurors will have me back here before very long."
