According to previous biographies, Hepburn was something of a resistance hero, who rolled bandages for the wounded, allegedly helped harbour an Allied soldier (identity never discovered), hid secret messages in her sock, and so on and so forth. Matzen is to be congratulated, therefore, for conducting research in Holland and ascertaining that Hepburn, far from only performing in “underground concerts to raise money for the Dutch resistance”, actually danced to applause in a concert for the Wehrmacht, organised by her mother in July 1941. Five months later, Ella put together a Mozart festival expressly for the occupiers. Hepburn again appeared. None of this was to be divulged later.
