Incarnadine: Loch Lonach Scottish Mysteries, Book Five - Loch Lonach Scottish Mystery Series, #5

Ginny Mackenzie is thrust back into the role of clan investigator when the matriarch of a prominent Loch Lonach family dies, bequeathing her considerable resources to a man determined to destroy the Scots' way of life. The Patterson family left Chancie Mor thirty years ago. Maury Patterson, scion of the family and a state Senator from his adopted home in Illinois, has returned. He has plans for the Scots.
He likes being rich, and famous, and admired, but most of all, he likes power. Ambition and superstition reign in this modern take on Shakespeare's "Scottish Play."
