Adam Mitzner, The Perfect Marriage

This story has sort of a strange arc. Jessica and James are happily celebrating their first anniversary, but their "perfect marriage" was built on the backs of two destroyed relationships. Both exes are on the scene and suffering in their own ways from the betrayal of their former spouses, and Jessica's teenaged son is facing a grim medical diagnosis. James, meanwhile, is getting involved in a shady art deal with a sometime associate. So there's all that backstory, which goes on for more than a third of the book, and then suddenly everything changes: one of the characters is found dead, and now we're in the middle of a police procedural. Then it turns into a legal story and we watch the initial proceedings against the accused in some detail until, ultimately, the story rolls to an unsatisfying, unsurprising conclusion. It's not an awful book, but it doesn't make me eager to read more from this author.
