Mary was curled in a big chair with a book. Certainly the opportunity
was exceptional.

At the noise of his entry she sprang to her feet with a little cry.
"Oh, dear!" she exclaimed: "what a fright you gave me!"

Bob pushed the door. He laughed. "Did I?"; came towards her. "Are you
all alone? What a shame!"

"Minnie is in the kitchen, I think. Mrs. Chater said you wouldn't be
in to-night."

"Why do you think I came?"

"I don't know."

"I came to see you."

She gave a nervous little laugh and made to pass him.

Bob fell back a pace, guarding the door. "Don't you think that was
thoughtful of me?"

"I don't know what you mean. There was no need."

"What! No need! You all alone like this when all the rest are enjoying
themselves!"

"So was I. A long evening with a book."
