"Please, ma'am, I don't know. It's a red-haired girl."

"But, Jane, be serious. There is no red-haired girl in the house."

"I know there ain't, ma'am. But for all that, she spies on me."

"Be reasonable, Jane," I said, disguising the shock her words produced on me. "If there be no red-haired girl in the house, how can you have one watching you?"

"I don't know; but one does."

"How do you know that she is red-haired?"

"Because I have seen her."

"When?"

"This morning."

"Indeed?"
