KATHERINE. Yes.
OLIVE. [Reading from the letter] "My dear Heart." Does he always call you his dear heart, Mummy? It's rather jolly, isn't it? "I shall be home about half-past ten to-morrow night. For a few hours the fires of p-u-r-g-a-t-or-y will cease to burn—" What are the fires of p-u-r-g-a-t-o-r-y?
KATHERINE. [Putting away the letters] Come, Olive!
OLIVE. But what are they?
KATHERINE. Daddy means that he's been very unhappy.
OLIVE. Have you, too?
KATHERINE. Yes.
OLIVE. [Cheerfully] So have I. May I open the window?
KATHERINE. No; you'll let the mist in.
OLIVE. Isn't it a funny mist-all flat!
