MARY: I’ve been studying the story of Andromeda; do you know it?

MATTHEW:  Why?

MARY: Her father was King Cepheus, whose country was being ravaged by storms. And, in the end, he decided the only way to appease the gods was to sacrifice his eldest daughter to a hideous sea monster. So they chained her, naked, to a rock.

MATTHEW: But the sea monster didn’t get her, did he?

MARY: No. Just when it seemed he was the only solution to her father’s problems, she was rescued.

MATTHEW: By Perseus.

MARY: That’s right. Perseus. Son of a god. Rather more fitting, wouldn’t you say?

MATTHEW: That depends. I’d have to know more about the princess and the sea monster in question.
