The unlikely crime solving duo make a welcome return as retired actor John Chapel and disarming Welsh detective sergeant Janie Mallowan, alongside regular cast Alexandria Riley (Helen Baxter), Steffan Rhodri (DCI Barry Clarke), Melanie Walters (Yvonne Mallowan) and Rithvik Andugula (DC Evan Chaudhry). Series two picks up a few months after the events of series one, Janie has been promoted to Detective Inspector and is busier than ever, with paperwork stacking up quicker than she can clear it. To make matters worse, she’s been ignoring John since finding out he’s been dating her mum. Janie’s hand is forced after a murder in a Community Payback group when DCI Barry Clarke forces her to bring John Chapel in as the department's consultant.
