Quote context

[...]

- I bribed one of his servants to get me an impression of the lock. Here's the key.

- I waited until Dorian came down here to Selby and then I let myself in.

- I know you'll despise me for stooping to such measures, but I'm not important. It doesn't matter what happens to me or even what you think of me if I can stop you from marrying him.

- What did you find in the room?

- Nothing to help me really. It's just an old schoolroom with books and things and there's a huge portrait with a covering over it.

- A portrait? Of whom?

- I don't know. The original must be a monstrous person, if an original exists.

- It has a vague family resemblance to Dorian. A sort of middle-aged, mad, gruesome uncle with a debauched face and blood all over him.

- It was painted by your uncle. My uncle never painted such a picture.

- He signed it.

- I've been counting so much on finding something to help me that I decided perhaps it was just stupid jealousy on my part that I've been doing Dorian a great injustice.

- I had an impulse to come down here and make a clean breast of it to both of you. Give you my blessing and ask your forgiveness.

- Can you describe the portrait in greater detail?

- There's a curious cat in it. Like the one in Dorian's drawing room. Only in the portrait the eyes shine in an evil way that's indescribable.
