The Gone
9pm, BBC Two
“We believe no connection exists between recent events and the Goat Man killings.” In the first season of this crime drama, Theo Richter (Richard Flood), an Irish detective in New Zealand, teamed up with a Māori counterpart, Diana Huia (Acushla-Tara Kupe), to solve the case of a missing Irish couple. As the show returns, two people are on trial for murder. But Theo can’t leave just yet – an Irish journalist, Aileen Ryan (Carolyn Bracken), is missing. As they look for her, the town speculates over the historical “mountain murders” that were never solved. Hollie Richardson
