When the body of Susan Bartlett, wife of local farmer Simon Bartlett, is discovered in Setwale Wood, local villagers readily assume she committed suicide due to her inability to have a child. But when Barnaby discovers the timestamp on her suicide is from seven hours after her death, the search for a suicide motive morphs into the hunt for a killer. Barnaby & Troy quickly find themselves thrust into a whirlwind of witchcraft, ancient potions, infidelity and land feuds that expose a chilling example of the consequences that can follow when parents believe they always know best.
