Query: GRANT MYSTERY

I was sort of in a new zone on this book as I admire US Grant from the Civil War but as a mystery slueth? I was pleasantly surprised as the story is logical and follows a believable path in history. The weaving of the Grant family into the story made it seem more like non fiction, which I normally read. A good who dun-it as I did not solve until the end. Looks like the start of a good series.
