“Huh?” Helen exclaimed as she looked at the old lady in surprise. “You’re Lady Acker?! Please come in! Mr. Christian, please come in too!”

With that said, she quickly opened the door.

Based on Charlie’s instruction, she immediately concluded that the old lady’s purpose in coming here must be to find out clues about Charlie.
