In this week's episode, Alice and Helen discuss 2008 film Affinity, an adaptation of the Sarah Waters novel of the same name from 1999. Affinity is an atmospheric tale of Victorian crime and spiritualism, in which Margaret Prior (Anna Madeley), a wealthy 'lady visitor' to Millbank Prison becomes fascinated by inmate Selina Dawes (Zoe Tapper), a disgraced spiritual medium. In this installment of our Murder Girls series, we talk about historical fiction's fascination with queer women criminals, modern depictions of unjust historical prison systems, the problems of adapting huge Neo-Victorian novels, the material underpinnings of the spiritualist movement - and whether the metaphysical realm belongs to the girls and the gays.
