The season premiere of Broadchurch is about digging: digging into the past, and, quite literally, digging up a body. The body? Danny Latimer’s for a new autopsy. But metaphorical bodies are also being unearthed as the British mystery returned. When season 1 came to a close, it seemed so certain that Joe Miller was the culprit, but now he has pleaded not guilty, reducing the town of Broadchurch to shambles again.
