It's slightly longer than two sentences, but it's only two lines in the book, so I went wild (because you needed that to know what Wani was talking about).
"Wani drew the powder into two long lines. 'You'd better close the door,' he said.
Nick lingeringly disengaged himself: 'Yeah, we've only got a minute.' He pushed the door to and came forward to take the rolled £20 note." (p. 190)
Well, there you have it... evidentiary proof that The Line of Beauty is probably a wholly inappropriate book for many people to read. It could have been worse, on the other side of the page lines 7-12 were filled with a description of a hand job. It is filled to death with homosexuality (described in such vivid detail that is difficult to imagine how the author who is married with two kids knows how to write these scenes so explicitly) and so much clubbing and coke-snorting that you feel like you've been thrust straight back in 1986.
However, this book won the Man Booker Prize in 2004, and the character of Nick is tragic and keeps me sucked in (for a reason I can't fully understand). So, I keep reading it because I'm sure they'll be something redeeming and worth learning, right?
