I think this would have been just as good a story without the secondary mystery (your mileage may vary)
Miss Eleanor Hancourt was living as Nell Court as a governess, escaping family scandal and predatory fortune hunters, taking the best care she can of her employer's wards when she bumps into a man she assumes is the new estate manager, he's actually the Earl of Barberry, her employer, but he goes with the fiction to find out more about his estate. Along the way they fall for each other but both have issues with the other finding out who they are, can the love survive the truth.
And then there's the treasure subplot that just didn't really add to the story. The ending of it was all wrapped up way to easily as well and I felt like there were parts missing when the villains were confronted, it felt quite rushed. Not a bad read, has potential.
