Hmmm, I think this could have been much sharper if it was shorter, mainly because the "mystery" is so obvious from very early on - and I'm not exactly Miss Marple when it comes to these things. That or putting more emphasis on the burgeoning romance, rather than dwelling too much on the family, most of whom I disliked anyway and couldn't have cared less about. But then I felt the same way about nearly everyone in Gatsby, which as I understand it is the inspiration for this story. 
 However, as always, Josh Lanyon is an excellent writer who kept me reading to the end, long after I would have given up on a lesser author.
