“Why didn’t he introduce her then?” Dorothy said shortly. “It serves me right.”

“What serves you right?”

“For allowing you, as well as myself, to become so familiar with a strange man.”

“Oh!” murmured Tavia, slowly. “It’s not so bad as all that. You’re making a mountain out of a molehill.”

But Dorothy would not listen.
