Ghost in the Machine

Detective Constable Scott Cullen of Lothian and Borders has only been three months in CID as a full DC. He is assigned a Missing Persons case which has stretched his uniform colleagues. Caroline Adamson - a young, recently divorced mother from Edinburgh - has disappeared whilst on a date. The more Cullen digs into her disappearance, the more he unravels her private life. Who was she on a date with? What happened during her divorce from Rob Thomson? As Cullen's own private life gets messier and the relationship with his DI deteriorates, Caroline's body turns up and he finds himself hunting for a ghost in the machine.
