The man who was Thursday

The Man Who Was Thursday: A Nightmare is a novel by G. K. Chesterton, first published in 1907. Although it deals with anarchists the novel is not an exploration or rebuttal of anarchist thought; Chesterton's ad hoc construction of "Philosophical Anarchism" is distinguished from ordinary anarchism and is referred to several times not so much as a rebellion against government but as a rebellion against God, and takes on many aspects of nihilism. The book has been referred to as a metaphysical thriller.
I'm enjoying listening to bits of it via Radio 7 and reading it (on my PDA!) via ManyBooks.com.
It's a cracking book!
