"An abortion doesn't cost a quarter of a million dollars. I'll pay, but it must be reasonable."
"The amount isn't based on the cost of an abortion. It's the amount I think your continued respectibility is worth to you."
"Blackmail! Extortion!"
"Yes, I think that's what it's called. I don't know the exact difference. But it's a single payment, unless something goes badly wrong sometime in the future. But I don't expect that."
"I can't believe this! You let me get you pregnant just for the money? What about the baby? You never intended to keep it? You would kill your baby just for the money? You planned this whole thing?"
"Believe it, dearest uncle. I would do a lot for that kind of money. You get along in this world using the tools you have. I have my body and my brain. So is it a deal? Or would you prefer the exposure, and accept the baby as yours? Your sister's daughter's baby as yours. Grandmother would not be pleased to learn that. She might well change her will. You could lose more money keeping the baby than paying me off. Grandmother has a very conservative attitude towards fornication, adultery, and especially incest. That's why I acted the first chance I got. She might have died before I got pregnant."
"You got pregnant on purpose. You said you were on the pill."
"I lied about that, Uncle dear."
"You are going to kill your unborn child! What about adoption?"
"Not an option. It the baby is born, it's yours. If it is to remain unborn you are going to pay for it. So again, is it a deal?"
"Yes, it's a deal."
"I leave for California the day after I receive your check. Don't wait too long, I'm already two months along."
The story gets around that she went to California to have an abortion. No one knows or guesses who the father is. She gets a bad reputation from the incident and isn't contacted by her family. She doesn't contact them either. She just disappears.
She doesn't have an abortion. She has the baby. She goes to college, gets a job, raises the baby. I don't know what happens after that.
Grandmother dies. She leaves her wealth equally to her son John and her daughter Mary.
Granddaughter Elizabeth contacts her mother on the occasion of grandmother's funeral. Elizabeth won't attend the funeral but asks mom to come to California to visit. Mary agrees. She has the wealth and the freedom to do that now that now.
Elizabeth tells Mary everything. Mary now has a grandson.
"I didn't want anything to get back to Grandma. She didn't need to hear about this. But now you're the only one who doesn't know about the pregnancy.
"Does John know about the baby?"
"John paid a quarter of a million dollars to have the baby killed. I wouldn't want him to think he had wasted his money."
"Will you ever tell him?"
"No. But I want you to have a say in what I tell little Peter. I don't plan to tell him anything for ten of fifteen years. His situation isn't that unusual here anyway. He doesn't need a story. But eventually he might need to know his ancestry. I want your opinion about that."
