Rick sighed. His entirely career was pretty much questioning amateurs who didn't have much in the way of memory to begin with. Right now, he was questioning Lotte, and there was a good chance Lotte wasn't even there when this guy was around--it was the girl from the opera. (Such was the extent of Rick's knowledge of Phantom. He did not much care for that kind of culture.)
So right now he had a masked man without a mask, around his height, thin, with a voice in the lower register.
Great. That was only about half the state.
Rick pressed his lips together and the cool distance returned. "Well," he said, "let me know if something else comes up. Or if you see him..." He grinned at her, though it was truly just a gesture, "give me a call." He offered her his business card.
