"It's the last woman a man thinks of that he generally ends by marrying," said John.

"If he'd only think of her," said the Doctor, "he'd be safe enough."

"I know. It's his not thinking," said John; "it's his dashing into it with his eyes shut."

"Do you think," said Frances, "we'd better open his eyes?"

"If you do that," said Levine, "he'll marry her to-morrow."

"Yes," said the Doctor; "much better encourage him, give him his head."

"And fling her at it?" suggested Sophy.

"Well, certainly, if we don't want it to happen, we'd better assume that it will happen."

"Supposing," said Frances presently, "it did happen—what then?"

"My dear Frances, it would be most undesirable," said John.
