Rick Davis is an agent with the American Secret Service.
So far lacking the first issue of the 4-issue magazine which apparently contains the back-story of how Davis joined the Secret Service, I have only the information contained in his publisher's but it is an excellent source of data. According to that data, Davis had worked in law enforcement for some time while awaiting the opportunity to test for admittance into the Service. When the chance for the test came, he passed "with flying colors". Very shortly ("within hours") he was on his first assignment.
Since the Service has a rigorous training procedure its rookie agents had to go through, either Davis' experience was deemed sufficient or the need for his talents were so great normal operations were bypassed. Whatever the reason, he got his credentials and was off.
How long he had been a policeman is not certain but based on his age it likely was a few years for Davis is not a spring chicken in his Service adventures, appearing to be in his early 30s at least. He has slightly wavy brown hair. He is clean shaven and, as was the custom during the 50s, invariably wore a suit no matter where he went. He often added a long trenchcoat to his ensemble and he obviously had several for sometimes he is seen in a brown one and other times it is canary yellow.
In one of his adventures he states that he spent a couple of days preparing for a mission to Czechoslovakia including brushing "up on the language so that no accent would betray me to a native". How he came to speak Czech already is not mentioned. A different assignment has him adopting a Cockney accent well enough to fool London bobbies.
Another mission has him flying a plane, in this case an old style bi-plane which he was able to handle but obviously preferred the more modern craft. When and how he learned to fly is not known.
About his personal life we learn absolutely nothing. There is no mention of family or friends or anyone close to him. Being an internationally traveling agent with the Secret Service must be a very consuming occupation.
