What is the tie between miss emma and henri picot? how does this tie figure into the ladies scheme?

Miss Emma was a servant in Henry Picot's home. He was a wealthy landowner, and Miss Emma wanted his assistance. She was frightened that Jefferson would die alone like an animal, and she wanted him to use his influence in getting the jail to allow someone other than her to visit. Miss Emma was an old woman, and it would have been phyisically impossible for her to go back and forth from the prison.
