Yukiko walked over, her mouth stretching into a feline grin at the sight of Murakami. Naomi followed a moment later. She was wearing another elegant black cocktail dress, this one silk, fitted at the waist but loose above it. The diamond bracelet glittered on her left wrist as before. She saw me, and her expression started to break into a smile that aborted itself when her eyes shifted from my face to Murakami's. She must have known him, and, based on the story I had told her, obviously didn't expect to see us together. She was trying to process the incongruity, certainly. But the suddenness of her change of expression told me there was more. She was scared.
