Haworth 1847. Anne and Emily Bronte have had their books accepted for publication, while Charlotte’s has been rejected everywhere, creating a strained atmosphere at the parsonage. At the same time, a shocking court case has recently concluded, acquitting a workhouse master of murdering his wife by poison. Everyone thinks this famously odious and abusive man is guilty. However, he insists he is many bad things but not a murderer. When an attempt is made on his life, he believes it to be the same person who killed his wife and applies to the detecting sisters for their help. Despite reservations, they decide that perhaps, as before, it is only they who can get to the truth and prove him innocent, or guilty without a shadow of doubt.
