This is a review in The Guardian about a new book by historian Deborah Cohen. It looks at the changes in attitudes to privacy and secrecy in the family over the last 200 years.
The relevance to this blog is in the 6th paragraph, which mentions "those permanent bachelors without whom no Victorian home was complete".
