HaBO: Irish Twins & a Horse Drugging Ring

You did it! We figured this one out! It is a truth universally acknowledged (by me for certain) that the Bitchery pretty much knows everything, and really, it's true. Scroll down to see the solution for this HaBO - and many thanks!

This HaBO request comes from Florencia, who is looking for a book with some crazy horse-related scandals:

This was read several years ago. The premise of the story: Irish brother and sister. The brother is very good with horses and goes off to work for a horse farm that is also heavily involved in the derby-racing world. But suddenly, he stops writing his sister and so she thinks something happened to him. Her and a friend (I think) travel to where his last letter came from, which happened to be a horse-racing townShe is as beautiful as Aphrodite in heat, so of course a very powerful and high-stationed man takes interest in her, and thinks she is part of the ring that’s drugging horses before the races. In true stalker fashion, he follows her around and chases her into woods and so on.

The Irish sister ends up dressing up as a boy to search for her brother, her and the high-stationed gentleman have sex in an abandoned house, his office as she is reading over ledgers, and several other places. They find her brother and dismantle the illegal ring. She refuses to marry the gentleman, but he courts her heavily. After she says, “Fine, I will have you,” she gets kidnapped by the head of the drug ring, who was part of their society circles, and she gets shot on the ear saving her soon to be husband. The end.

Well, all right then! I don’t know this book,  but with all this stuff happening, I can only imagine it’s 800 pages long.
