The Australian murder mystery series Darby and Joan was a big hit during its first season, and now the Acorn TV original has returned for season 2. The series centers on a widowed former nurse who traverses the Australian countryside with a retired detective in search of answers regarding her late husband’s death. Fitting squarely in the category of a cozy murder mystery, Darby and Joan is unique because it focuses on the depth of the characters and uses its mystery framework as a backdrop to explore Joan and her personal journey.
