Mary

“Each of the dancers took a partner, the living with the dead, each to each. Bod reached out his hand and found himself touching fingers with, and gazing into the grey eyes of, the lady in the cobweb dress. She smiled at him.
“Hello, Bod,” she said.
“Hello,” he said, as he danced with her. “I don’t know your name.”
“Names aren’t really important,” she said.
“I love your horse. He’s so big! I never knew horses could be that big.”
“He is gentle enough to bear the mightiest of you away on his broad back, and strong enough for the smallest of you as well.”
“Can I ride him?” asked Bod.
“One day,” she told him, and her cobweb skirts shimmered. “One day. Everybody does.”
“Promise?”
I promise.”
