'I remember you once told me about mockingbirds and their special talents for mimicry. They steal the songs from others, you said. I want to ask you this: how were our own songs stolen from us, the notes dispersed, while our faces were turned away?'

Berlin, 1936. Ernst Schafer, a young, ambitious zoologist and keen hunter and collector, has come to the attention of Heinrich Himmler, who invites him to lead a group of SS scientists to the frozen mountains of Tibet. Their secret mission: to search for the origins of the Aryan race. Ernst has doubts initially, but soon seizes the opportunity to rise through the ranks of the Third Reich.

While Ernst prepares for the trip, he marries Herta, his childhood sweetheart. But Herta, a flautist who refuses to play from the songbook of womanhood and marriage under the Reich, grows increasingly suspicious of Ernst and his expedition.

When Ernst and his colleagues finally leave Germany in 1938, they realise the world has its eyes fixed on the horror they have left behind in their homeland.

A lyrical and poignant cautionary tale, The Hollow Bones brings to life one of the Nazi regime's little-known villains through the eyes of the animals he destroyed and the wife he undermined in the name of science and cold ambition.
