I was glad I wasn’t having to lie, because I knew her eyes would find me out. Rambo was rubbing himself blissfully up against her leg, and I wondered how long it would be before he realized that two of us couldn’t be the same person. Still the Black Queen said nothing.

All those chessboards, and you said he was a chess nut. And you told me you were going to New York to see your son. I guessed it all along. That’s where you went, didn’t you? He won. He beat Purple. My dad says he’s a genius, a pure genius.” Suddenly her face softened, and she laughed. “It’ll take more than some fool machine to beat my son,” she said.
