The madam/procurer has been writing a book. A diary of sorts she started the day she was arrested. It is many hundreds of pages now and with an editor. She doesn't need any money, so she doesn't have to worry about those making money off crimes laws. She would give it away for free. Several publishers want the book. Will she end up dead first?

Honestly her life story seems like a good start. The client list will just be a list of names.
