When Naomi Macaulay disappears after a night out, Detective Inspector Mike Nash soon discovers that her disappearance may be connected to a much older web of crime. As the investigation develops, the murder of solicitor Ormondroyd reveals missing files, suspicious financial records and a mysterious message: “Must find Sam.” Nash begins to suspect that the dead solicitor had uncovered something someone was desperate to keep hidden.
Meanwhile, independent auditor Patricia Wain travels north to investigate suspected financial malpractice at Shires Financial Services. Before she can begin her work, she is followed, threatened and eventually disappears. Her case draws Nash into a dangerous investigation involving fraud, corporate secrets and people willing to kill to protect themselves.
As the seemingly separate cases begin to converge, Nash and his CID team uncover links stretching back years, involving the Macaulay family, Bishopton Investment Group and a series of unexplained deaths and disappearances.
With lives at risk and the truth buried beneath layers of deception, Nash must discover who is behind the killings before another victim becomes both dead and missing.
