Billie Carlson

Billie Carlson left the police force under a cloud. Once a promising young officer, she now works as a private investigator, rooting out insurance scams and spying on cheating spouses. One morning a distraught young woman comes into her office saying that her baby has been stolen. Her story seems unbelievable, yet something about her makes Billie want to help - Billie knows what it's like to lose someone too. To get to the bottom of the case, Billie must rattle some dangerous cages and rely on old police friends for inside help.

PI Billie Carlson is in Cleveland following a lead on the whereabouts of her son, Lucas. But when the trail goes cold, she is forced to return to Glasgow and a life of waiting and praying that one day she might see him again. Back in the office and ready to throw herself into work, she picks up a call from Lars, an old friend from her teenage years in Sweden. He tells her some devastating news. His younger sister, Astrid, was found dead in the Highlands, frozen to death with traces of drugs and alcohol in her system.

Life has changed for Private Investigator Billie Carlson. After years of chasing down every lead possible, she's finally found her son, Lucas, and brought him safely home to Glasgow. One afternoon, Billie gets a call from an unknown number. The man on the end of the phone refuses to tell her his name, but he explains that his brother, Omar, is being held in prison after stabbing two men outside a block of flats. He wants Billie to investigate what happened that night and find out any information that might help Omar. Reluctantly, Billie takes on the case.

The future is looking bright for Billie Carlson. With her child safely home and a new relationship on the horizon, she hasn't felt so settled in years. But when Billie takes on a new client, Elizabeth Fletcher, it's clear trouble is imminent. Elizabeth has killed a man in self-defence. She met him in a bar but he'd turned aggressive, attacking Elizabeth in the middle of the night when she caught him going through her husband's desk drawers. Refusing to go to the police for fear her husband will find out, Elizabeth wants Billie to work out who he was - and what secrets he was looking for.
