Dark Horse by Tami Hoag
I’ve read two others of hers, one unexpectedly a sequel to the other. The first one had a romantic sub-plot that was surprisingly captivating. The other, I don’t recall. Dark Horse also had a romantic sub-plot, one you could see coming from a mile away but that was ultimately touching. It had a complicated plot-plot and a complicated detective-protagonist.
The protagonist was torn up about a decision she’d made in the past that had caused someone’s death, but the decision wasn’t convincingly the cause of that death. And then at the end of the book she chose to make the same decision again, only this time without causing a death. So . . . lesson learned? Guilt resolved? Seemed like a push. Other than that quibble, I enjoyed the book.
