"Yes, not quite a week. My wife has not been well. We were recommended here that she might do the cure."

"I see," Wentworth said, somewhat relieved at finding himself on the way to an explanation. "Well, this is a splendid place, I believe, for the people that it cures," he added sapiently.

"No doubt," Rendel said.

"Oh! dear me, yes," said Wentworth, unconscious that each of the names he might enumerate would represent to Rendel a possible inexorable judge. "Half London is here: Lady Chaloner, Pateley—all sorts of people."
