“Oh!” said Bob, “why, that was a lady’s——”

“I know it,” rejoined the voice quickly. “Oh dear. It is mine. I am a lady.”

“Pray wait one moment, madam, and I will strike a light.” [[293]]

“It is useless. You cannot see me, I am invisible,” replied the voice.

“Indeed!” ejaculated Bob, “that is a pity. However, I will return to you what I found upon one condition.”

“What condition?”

“Tell me who you are.”
