Then Halcyone asked politely if he would have a second cup of tea, but he refused and again addressed Cheiron, ignoring her.

Their conversation now ran into philosophical questions, some of them out of her depth, but much of the subject interested her deeply and she listened absorbed.

"It was invented so that the Master here and I should pull each other's theories to pieces; that evidently was its aim from the beginning of time.

I do not know if it has any other good." "Everything is so very simple," said Halcyone.

"To have to argue about it must be fatiguing." "You find things simple, do you ?" asked John Derringham, now complacently roused to look at her.
