Isobel Blackthorn

A Perfect Square Isobel Blackthorn

On a winter's day in the Dandenong Ranges of Australia, pianist Ginny returns home to her eccentric mother, Harriet, trying to find out the truth about her father's disappearance. In an effort to distract her daughter's interrogations, Harriet proposes they collaborate on an exhibition of paintings and songs.

Meanwhile, on the edge of Dartmoor, artist Judith paints landscapes of the Australian Outback to soothe her troubled heart, as her wayward daughter Madeleine returns home... and fills the house with darkness.
