The Lonesome Autocrat is Alice Zogg’s fourth mystery novel.  As in the author’s three previous books, phenomenal private investigator R.A. Huber cracks yet another mind-boggling homicide case.  The lady detective is forced to cut short her European vacation when she stumbles upon the crime while visiting her childhood friend Erika Graff in a village near the resort town of Davos, Switzerland.  Erika’s father, eighty-four-year-old Otto Sonderegger, summons his sons to his estate and makes an announcement.  The old autocrat causes animosity within the family when he makes his proclamation, which leads to murder.  When the killer strikes down a second victim, Huber connects the dots but barely escapes with her own life when the murderer turns on her.
