Marge Sherwood: I don't believe a single word you've said.
Tom Ripley: You're shivering, Marge. Look at you, Marge. Can I hold you? Will you let me hold you?
Dickie Greenleaf: Now you'll find out why Ms. Sherwood shows up for breakfast, Tom. It's not love, it's my coffee machine.
Peter: Tom is crushing me.
Tom Ripley: Nothing is more naked than your handwriting. See how nothing's quite touching the line? That's vanity.
Dickie Greenleaf: Well, we certainly know that that's true.
Marge Sherwood: Tom was telling me about his journey over. Made me laugh so hard I almost got a nosebleed.
Dickie Greenleaf: Is that good?
Marge Sherwood: Shut up.
Dickie Greenleaf: I'm sorry. I'm sorry. I'm despicable. But I love you. Do you love me?
Dickie Greenleaf: How could it take an hour to find an ambulance?
Marge Sherwood: She was already dead, darling.
Dickie Greenleaf: I don't know why people say this country is civilised. It isn't. It's fucking primitive.
