Ada's Death

A small town murder at a family reunion seems almost impossible to solve.  There’s no physical evidence; the obvious suspects all have alibis; and there’s very little time to interview the slew of visiting relatives before people pack up to leave for home.  The police are grateful for the cooperation of the victim’s clever niece, and a local doctor provides a quick autopsy.  But as the investigation progresses - or fails to progress- they begin to wonder?  Just how helpful is that clever niece?  And what secret is the good doctor trying to protect?
