Little Demon finds investigator Plant back in the iconic paradise of Byron Bay, hired by ageing rock ‘n’ roll journalist Rock Richmond whose computer with his history of the alternative communes has been stolen. Plant’s rural retreat is invaded by conspiracy theorist Fullalove, who figures Richmond had been writing about rumoured Cold War arms caches and secret militias. Plant’s inquiries involve Rock’s wife, a barrister specialising in drug cases, his girlfriend the mysterious Madimi, and caravan park owner and rifle club president Jake, a former army officer who used to run a commune.
