I'm looking for the title and author of a book. It's fiction and involves a murder.
I'm not sure when I read it or when it was written, but I believe the story predates the founding of Google. It's all about how data mining will rule the world.
The husband is a lawyer and his wife is a software engineer.
The wife is working on something similar to Google. The husband is going to handle the sale of the software. He gets killed before the sale goes through. She has an important mentor. He stresses how important the software will be - both for power and money. She turns to him after her husband is killed. As it turns out, he is part of the group that kills the lawyer to stop the sale.
