Draco had had to find the blasted ring to let himself into Diamond. It wasn't that he didn't covet it and keep it safe enough, Diamond was prestigious and important for that reason alone, not to mention the socializing that could be done there, but he didn't frequent the place the way some others did, and he didn't wear the damned ring when he wasn't planning on stopping in.
Still, he arrived on time, and a few minutes later the attendant was leaving him at the door to the private room where he assumed Smith was. He knocked once, curtly, then opened it - glass of brandy already in his hand.
