Mark McPherson: When a dame gets killed, she doesn't worry about how she looks.
Waldo Lydecker: Will you stop calling her a dame?
Waldo Lydecker: Love is eternal. It has been the strongest motivation for human actions throughout history. Love is stronger than life. It reaches beyond the dark shadow of death.
Waldo Lydecker: If you come a little bit closer, my boy, I can just crack your skull with my walking stick.
Waldo Lydecker: You'd better watch out, McPherson, or you'll finish up in a psychiatric ward. I doubt they've ever had a patient who fell in love with a corpse.
Shelby Carpenter: For the last time, Louise, will you marry me?
Louise, Ann's Cook: No, but I cooked some chicken liver for you.
Mark McPherson: Nice little place you have here, Mr. Lydecker.
Waldo Lydecker: It's lavish, but I call it home.
Waldo Lydecker: In my case, self-absorption is completely justified. I have never discovered any other subject quite so worthy of my attention.
Mark MacPherson: On Saturday when our men went to the hotel to tell you that Laura Hunt was dead you seemed sincerely shocked.
Shelby Carpenter: I was. I hadn't expected that mistake.
Mark MacPherson: But you had your alibi ready no matter who was dead.
Waldo Lydecker: Have you ever been in love?
Mark McPherson: A doll in Washington Heights once got a fox fur outta me.
Waldo Lydecker: My dear, either you were born on a extremely rustic community, where good manners are unknown, or you suffer from a common feminine delusion that the mere fact of being a woman exempts you from the rules of civilized conduct.
