The Fall of Optimum House is Alice Zogg’s latest mystery novel featuring R.A. Huber.  After solving a murder case in Switzerland in “The Lonesome Autocrat,” the athletic yet chic private eye is back in California.  Iris Camden, owner of Optimum House, engages her to find out who’s responsible for the bizarre thefts and pranks at her facility.  Huber decides to send her newly hired young assistant, Andi, to pose as a modeling school student at Optimum House in the Big Bear Lake area.  Rookie Andi handles the investigation quite well and soon suspects that a pool drowning treated as an accident by the authorities is in fact murder.  When another homicide is committed, it is time for Huber to make a trip to Big Bear for herself.  So the seasoned lady sleuth and the novice put their heads together and crack the mystery, but not before the killer strikes again and threatens R.A. Huber’s life.
