Chief Insp. Hubbard: There is evidence however that he was blackmailing you.
Tony Wendice: Blackmail?
Mark Halliday: Yes, I'm afraid it's true, Tony.
Chief Insp. Hubbard: And you suggest that he came in by the window. And we know that he came in by that door.
Margot Mary Wendice: But he can't have come in that way. That door was locked. And there are only two keys. My husband had his with him, and mine was in my handbag. Here.
Chief Insp. Hubbard: You could have let him in.
