Crooked House (2017)

Charles Hayward: Is everything all right?
Edith de Haviland: Do you know anything about moles?
Charles Hayward: No. I'm afraid not.
Edith de Haviland: I have an arsenal of other weapons, of course, traps, poisons. Sometimes I use holly. It pricks them, do you see? Makes them bleed. Moles are hemophiliacs. Little bleeders. Like some European royals. Though I do find a shotgun best expresses my feelings.

Sophia Leonides: We're a very odd family, Charles. There's lots of ruthlessness in us and different kinds of ruthlessness. That's what's so disturbing. The different kinds.

Charles Hayward: Anything you'd like to tell me?
Josephine Leonides: Not yet. You see, I read detective stories. And a good detective will take time to gather evidence... and question everyone before solving a case. The murderer is never the one you initially suspect.

Edith de Haviland: [Aristide Leonides was a] little man, Mr. Hayward, who cast a large shadow. A very large and rather crooked shadow.

Josephine Leonides: Did you find many clues?
Charles Hayward: You know, Josephine... the first round of interrogation is not so much about finding clues... as it is about getting a sense of who you're dealing with.

Charles Hayward: May I ask you a blunt question?
Edith de Haviland: They're the only interesting kind.
Charles Hayward: What's wrong with people in this house?
Edith de Haviland: It is a blunt question indeed.
Charles Hayward: Sorry.
Edith de Haviland: Don't be. Passion. It is a hothouse of suppressed passion. This is what happens when the person you love the most in the world... who you would give your life for... is actually the same person that you hate the most... I'm certain you understand, Mr. Hayward. You wouldn't be in this house yourself otherwise, would you?

Charles Hayward: Any of them could've done it. They all had means. They all had opportunity.
Chief Inspector Taverner: Motive?
Charles Hayward: Anger, jealousy, love, greed. Take your pick.
Chief Inspector Taverner: So no communist? No Las Vegas mafia? No CIA conspiracy? We're investigating too. Quietly. But you can go in the house without a warrant. Get back in there and find out who killed the bloody midget.

Josephine Leonides: I hear you're making progress. But you won't be the one who solves this case. If anything, you're Watson.
Charles Hayward: Is that right? Well, why don't you enlighten me, Holmes?

Josephine Leonides: I'd say we're due another murder. Don't you think, Watson?
Charles Hayward: Another murder, Holmes?
Josephine Leonides: Well, there's always a second murder. Someone who knows something is bumped off... before they can reveal what they know.

Edith de Haviland: Well, then, Charles. How about a blunt question for you, then? What are murderers like?
Charles Hayward: Well, you. And me. Everyone. Hot-blooded. Cold-blooded. They do share one or two traits. Vanity. A distorted morality. A lack of empathy. And murderers tend to feel that they are above... the rules and laws that govern ordinary mortals.
Magda Leonides: Well, that description fits every member of this family.

Edith de Haviland: Well... always leave a party at its height... when you're most enjoying it.

Charles Hayward: You listen to me. I daresay you are extremely clever. It won't be much good to you if you're not alive long enough to enjoy the fact. Don't you understand, you foolish child, that so long as you insist... on keeping secrets, you put yourself in imminent danger?
Josephine Leonides: Of course I do. But in some books, person after person is killed. You end by spotting the murderer because he or she... is practically the only person left. We must see what happens next.
