I’ve been binge listening to this series and somehow missed book one but it didn’t really matter with regard to getting to know the characters and their backstories. Detective Inspector Rowan Jackman leads the team. He’s a private person from an affluent background, well respected and liked, and is good at motivating his team. His passion is horses. Detective Sergeant Marie Evans is a widow who lost her husband in a motorbike accident. She’s able to assess situations and people with accuracy and is nicknamed Super Mario by her colleagues. Marie’s passion is motorbikes.
