"It's a habit of mine to just get rid of anyone who gets in my way. You know that. You know that most of my work has been assassinations or Dark Arts potions in the last few years," Zada shrugged. "Thank you," she said to the vodka server. She tasted it. "Good quality. You know your vodka. This is one of the better Russian ones, is it not? And perfectly chilled. You are a fine host, Zerek. Send your lackeys away for a moment, though. We may have some serious business to discuss." Actually, she was accustomed to the smell of Dark Arts potions, so the odor that would have offended some mighty Gryffindor did not bother Zada at all. The smell was actually the trademark of fine potions work.
"These are your work, I presume?" she asked Zerek. "I take it you are quite an advanced potionsmaker. Some of these potions are extremely difficult to make and to get them to the quality that these clearly are. I might have use for your work--or rather, your services, if you might be interested. I apologize I did not think of you earlier. I presume you understand that the Carnivorous Tiger Rosehips have limited use because the Carnivorous Tiger Rose is so temperamental to work with. I did find, several years ago in Beijing, an ancient Dark Arts potion formula." She neglected to mention what she had had to do to procure it. That had been a rather grisly tale in itself. "At any rate, the potion claims to sort out, when mixed into a standard beeswax candle and is ignited, who is a dark arts practitioner and who is a white lighter. It claims to cast a different aura around them. My employer, I thought, might indeed have use for it in the near future. And he might have use for you, if you're interested."
She knew that Zerek knew her to always work alone, so she expected some degree of surprise from him when he learned that she had actually agreed to work on behalf of someone else and not her own ends. Not this time. This was almost unprecidented for her.
