Quote context

[...]

- Heh. When this is known, I shall be torn to shreds in every drawing room in London.

- Don't you think a gentleman should remove his hat in the presence of a lady, Parker?

- I never take off my hat except when I'm out of doors.

- She'll be as lovely as your sister was, Basil.

- Yes.

- But I'm afraid Dorian has stolen her heart from me too.

- I must congratulate you, Basil.

- Look at yourself, Mr. Gray.

- I should object strongly.
