Different twists to detectives

The private investigator was a very popular theme in the years during World War II, and especially immediately following it. There were several programs in which the stars were not Private Eyes strictly speaking, but had a different twist to that genre. Johnny Dollar was an insurance investigator. Mr. Keen was a Tracer of Lost Persons. The Saint was just a wealthy adventurer who got a kick out of helping people in distress. Pat Novak owned a small business and was ready to do whatever was required for a few bucks. And there were others. They spiced up the category with a little variety.
