Pushed into a miserable loveless marriage, Charlotte Rutherford Wylde finds her late husband has spent her entire fortune and more astonishingly, he has an entire family that he never bothered to mention.

But when they are thrown together to unravel the dangerous tangles the old man left behind, the two soon find that they only want to investigate each other.
