Many stories are told about the five Mansfield sisters . . .

They are haughty, thinking themselves better than their neighbours in the picturesque village of Little Nettlebed. They have taken the death of their grandmother hard. They are liars, troublemakers, untamed and dangerous… Accounts of their behaviour differ, but the villagers all agree that the girls are odd.

One long summer, a heatwave descends. Bloated sea creatures wash up along the parched riverbed, animals grow frenzied, ravens gather on the roofs of those about to die. As the stifling heat grips the village, so does a strange rumour: the Mansfield sisters have been seen transforming into a pack of dogs.

With the witch trials only a recent memory, hysteria sets in. Slowly but surely, the villagers become convinced that something strange is taking root in Little Nettlebed. And when a bark finally leads to a bite, the sisters will be the ones to pay for it.
