Lena

When Police Chief Alton Gravely and Officer Carothers escalate the feud between "Torreya's finest" and conjure woman Eulalie Jenkins by running her off the road into a north Florida swamp, the borrowed pickup truck is salvaged but Eulalie is missing and presumed dead. Her cat Lena survives. Lena could provide an accurate account of the crime, but the county sheriff is unlikely to interview a pet.
Lena doesn't think Eulalie is dead, but the conjure woman's family and friends don't believe her. Eulalie's daughter Adelaide wants to stir things up, and the church deacon wants everyone to stay out of sight. There's talk of an eyewitness, but either Adelaide made that up to worry the police, or the witness is too scared to come forward.
When the feared Black Robes of the Klan attack the first responder who believes the wreck might have been staged, Lena is the only one who can help him try to fight them off. After that, all hope seems lost, because if Eulalie is alive and finds her way back to Torreya, there are plenty of people waiting to kill her and make sure she stays dead.
