"Jealousy's quicker than the eyes, Andy." She leant forward again. "What did you see?"

"It seems disloyal to tell—disloyal to Harry."

"My loyalty's for Vivien!" she said. "What about yours?"

"Take it that what I saw justifies your fears about Harry," said Andy slowly. "I think—I'm not sure—I think he suspects I saw. I don't know whether she does." He was not aware that Isobel had made herself quite certain of his knowledge. "But it's nearly a month ago. You know Harry. I hoped it was all over. Only he seemed a little—queer."

"'Come and spend a quiet afternoon in the garden'—that was her invitation. Poor girl!"

"That's what you called her the first time I told you of their engagement."

"A nice quiet afternoon—sitting on the top of a volcano! With an eruption overdue!"

"It isn't possible to feel quite comfortable about it, is it?" said Andy.

The Nun laughed a little scornfully. "Not quite. Going to do anything about it?"
