This book really wants to be a bloodier version of And Then There Was None by Agatha Christie.  It takes that story and adds elements of the movies Ready or Not, and Knives Out.  And it’s not successful.  A woman has died and her children do not automatically inherit.  They have to survive a night and a blood bath as all fight for control of the house and the wealth that comes with it.  The cast of characters is something found in Clue.  It wants to be both a comedy and tragedy.  The biggest pet peeve for this reader is that the WHY is never really explained.  Just it’s always been done that way, or so and so wanted it that way.  That is not an explanation.  To be honest, if I was reading this I would have DNFed before I got to the halfway point.  However, I was listening to an audiobook, and the narrator did a fantastic job.  Between the voices, the inflections, etc.  The voice actor is what saves this book from being a complete waste of time.
