This is the full story of the right wing subversive organisation "The Economic League", which became known for its secret blacklisting activities on behalf of big business, but which has been also involved in anti-democratic conspiracies since the First World War.
This book was first made available online by the 1 in 12 Publications library.
Just discovered that Mike Hughes, author of this book, has a site with stuff on the Economic League, blacklisting, the spycops inquiry and related subjects: https://www.spiesatwork.org.uk/
