Yorkshire, 1845. A young woman has gone missing from her home, Chester Grange, leaving no trace, save a large pool of blood in her bedroom and a slew of dark rumours about her marriage. A few miles away across the moors, the daughters of a humble parson, Charlotte, Emily, and Anne Brontë are horrified, yet intrigued. Desperate to find out more, the sisters visit Chester Grange, where they notice several unsettling details about the crime scene: not least the absence of an investigation. Together, the young women realise that their resourcefulness, energy, and boundless imaginations could help solve the mystery - and that if they don't attempt to find out what happened to Elizabeth Chester, no one else will.
