The Stone Cypher (Mysterious Scotland Book 3)

They thought Orkney’s standing stones studied the heavens. It never occurred to anyone, the heavens might be studying us.

Magazine editor and part-time archaeologist, Gill McArdle is getting it together. Or at least, he thinks he is, until the death of a friend throws his life into turmoil. He’s on Orkney, researching an elaborate stone carrying an ancient religious motif. But he’s perplexed as the carving long predates any previous incidence of the symbol’s first use. Either someone is tampering with Orcadian archaeology, or Gill is facing a puzzle that can’t be resolved. Complicating his investigations, a secretive teenager passes Gill a notebook, packed full of numbers. At first, unexplained and impenetrable, the analysis starts to point to a mystery among the stars. As Gill battles to unlock the truth he realises he’s on the cusp of his most startling discovery yet.
