I smiled softly.

"I hope to God he hasn't fallen into the creek," said York's voice anxiously. "We'd better all turn out, hadn't we, and have a good hunt, before we tell the women?"

"That will be best," said Maurice. "I really am uncommonly anxious about him."

I stepped in quietly over the threshold. "In that case, Maurice," I said, "let me hasten to relieve your feelings."
