Dorothy: Mr. Porter, I came as soon as I could.
Mr. Porter: I'm glad you're here. We've got a problem. It's your mother.
Dorothy: What about her?
Mr. Porter: I don't know where she is, where any of them are. She took some of our guests out for a walk six hours ago.
Dorothy: Have you called the police?
Mr. Porter: Oh, sure. I'll tell them to be on the lookout for a bunch of old people in Miami. There's a lead.
