Edinburgh, December 1743.
Redcoat Captain Robert Catto is between the Devil and the deep blue sea.
His investigations have turned up compelling evidence of a real threat posed to the House of Hanover by a plan to restore the House of Stuart to the British throne.
His duty is to draw out as many Jacobites as he can find in Scotland’s capital and gather evidence against them, their names to be handed over to Duncan Forbes of Culloden, Lord President of the Court of Session, and Catto’s mentor.
Two of those dedicated Jacobite plotters are Patrick Rankeillor, surgeon-apothecary, and his daughter Christian Rankeillor. Yet with every day that passes and despite their very different and deeply held views, Robert and Christian are falling ever more deeply in love.
How is he to reconcile doing his duty with his feelings for Christian Rankeillor?
