Mr. sands and the Children

For Dr. Flint, he believed that the children would be better off if he sold them then if kept them. Dr. Flint would rather use revenge as blackmail then sell Linda's children. One day a man comes to Dr. Flint wanting to buy the children from him. The man finds a way to dry and convinced him to sell him the children. After a period of thinking he decides to sell Linda's children to him. Little did Dr. Flint know that Mr. Sands had made an agreement with this man, that once he had bought the children that he would then sell them to Mr. Sands. This is how Mr. Sands got ownership of them. 

The reason that Linda does trust Mr. Sands because there is nothing apparent to her that says not to. He has always been nice to her and never tried to forcefully sleep with her or ever black mailed her. He has told her that he would buy the children but Dr. Flint wouldn't allow him. She trusts him because he is the only man in her life that isn't family that is kind to her. I think Mr. Sands is a trustworthy guy. He hasn't given any reason for the reader to no think that nor has he ever tried to hurt Linda or her children. He helped the children get out of jail and told Linda he would provide for them and in the end that is what he does.
