- [Lady Agatha D'Ascoyne has been killed while sailing a hot-air balloon over London.]
I shot an arrow in the air; she fell to earth in Berkeley Square.
- While I never admired Edith as much as when I was with Sibella, I never longed for Sibella as much as when I was with Edith.
- The Reverend Lord Henry was not one of those newfangled parsons who carry the principles of their vocation uncomfortably into private life.
- It is so difficult to make a neat job of killing people with whom one is not on friendly terms.
- The next morning I went out shooting with Ethelred—or rather, to watch Ethelred shooting; for my principles will not allow me to take a direct part in blood sports.
The Parson 
- I always say that my west window has all the exuberance of Chaucer without, happily, any of the concomitant crudities of his period.
- Mr Elliot: Even my lamented master, the great Mr. Benny himself, never had the privilege of hanging a duke. What a finale to a lifetime in the public service!
- Prison Governor: Finale?
- Mr Elliot: Yes, I intend to retire. After using this silken rope, never again be content with hemp.
- Sibella Holland: Oh, Louis! I don't want to marry Lionel!
- Louis: Why not?
- Sibella: He's so dull.
- Louis: I must admit he exhibits the most extraordinary capacity for middle age that I've ever encountered in a young man of twenty-four.
- Sibella: He says he wants to go to Europe to expand his mind.
- Louis: He certainly has room to do so.
