At the end of 1931 during the misery of the Great Depression, Australia's left-wing federal government was voted out of office...but if it had instead won the election, could civil war have ultimately resulted? And why?
As Michael Cathcart recounts in his utterly engrossing book, by the early 1930s several anti-left 'secret armies' had become a sinister background presence in Australian society - and one of the largest was not only led by a major historical figure who was also a state police commissioner, but for a few tense days in 1931 it even partially mobilised.
But that's only one startling revelation that Cathcart highlights, along with his thought-provoking history of why and how the secret armies came about, and fortunately withered away.
Defending The National Tuckshop is an endlessly interesting account of a tense period in Australian history.
