Does anyone know the title of this book?

There are three main characters: Twin brothers (Nicholas and Anthony) and Justine (I think).
Justine is in love with Nicholas, but Anthony like Justine, so Nicholas ignores Justine. Later on at a party or something, Justine sneaks into Nicholas's room and they make love, without Nicholas knowing who he is sleeping with. During a tiger hunt, he finds out that his mystery lover is Justine. Then there is a horse race and Justine race the horse. The horse dies but they win the race. Nicholas shot his brother, Anthony because he betray them and he leaves Justine because she came between him and his brother.
