O‘Farrell was inspired by Robert Browning poem “My Last Duchess.” She describes the poem as “absorbing, shocking, technically perfect and so psychologically astute.” That last descriptor - so psychologically astute - actually describes her own novel perfectly. It‘s eerie and contained and remote yet defiant, bursting, and wild. It states simply: Even if you contain me, you cannot control me. Even if you end me, you never had me.
