"And how were you roused? How did you become aware of it?"

"I was not roused at all; the fact is I went asleep to Lady Belgrove's ball, and danced there and came back, and woke up in the morning without knowing I had been."

"And then, last night, I went in my sleep to Her Majesty's and heard Carmen; but I woke up in the conservatory here at early dawn, and I remember nothing about it."

"This is a very extraordinary story. Are you sure you went to the ball and to the opera?"

"Quite sure. My dress had been used on both occasions, and my shoes and fan and gloves as well."

"Did you go with Lady Lacy?"
