Peter Savage is a CEO of an engineering company.
Actually, EJ Enterprises, the name of the company using his two grown children's, Ethan and Joanna, first initials is "a combination of engineering, physics, and small arms". The item he shows off to a visiting friend is a "magnetic impulse gun", the technology of which is far beyond me but sounds very impressive.
Savage is nearing retirement age but has little thought of settling down. He might have once but when his wife of many years, Maggie, passed away, work provided a great distraction and he has made it pay off quite well.
For a man who many might think beyond the age to get into the kind of scrapes Savage will find for himself, Savage does land into a good deal of trouble here and there but his intelligence and his experience and his tenacity help him come out on top.
