A mutlitple car-crash on the M40 near Oxford. Doug Mullen rescues a mother and daughter. A video taken by an onlooker briefly goes viral. But public exposure brings its own problems. There is no accounting for who will see you and what that may lead on to. Mullen is a private detective, house-sitter and reluctant dog-sitter. He is also a bit of a soft touch when he encounters damsels in distress. While trying to support the damaged Natalie Swan and her rebellious daughter Ellie, he finds himself a man in demand. A missing refugee, threatening letters and an unexpected death are just the beginning. As Mullen tries to meet the needs of all those asking for his help, he - and his westiepoodle Rex - swiftly finds himself sucked into a web of deceit and murder. There are lies to be uncovered and the truth to be found, but sometimes it is hard to know which is better.
