"Over The Hump‪"‬

A father and son built a winery and restaurant under almost insurmountable obstacles in the arid Nevada countryside. When things are starting to go their way the unthinkable happens...the owner is murdered. He was a man that had few enemies, and his death looks like a senseless crime. One murder adds to another and authorities are baffled.
The son carries on holding the business together after he hires two private investigators, and their firm to look into his dad's murder. The detectives follow a bumpy road to solve the murders and come close to be victims themselves.
