Trip Callaway is a musician.
He blasts a pretty impressive trumpet in gigs all over the country, wherever someone is willing to pay to have a trumpet blasted and people wanting to be entertained by someone as talented as he is, which is quite a bit. While Callaway is still relatively new in showbiz, we are told that he has plans and aspirations when we read in the blurbs about his adventures which call him "the young, wise-cracking musician with dreams as big as the Hoover Dam".
Callaway has seen that impressive wall of concrete since he is living in Sin City when we first meet him in 1965. He has a gig playing at the Sands Hotel and Casino and while he is grateful for the work, he hopes it is just a stepping stone to bigger and better things with the fame and fortune he would love coming with it.
Our first meeting with him will not be one of the 'better' times since Fat Tony is out of patience to get the money that Callaway owes him and has sent Vinnie and Knuckles to show Callaway how serious he is, said proof resulting in Vinnie's fist - the size of an oil can - meeting Callaway's body. In case you were wondering, that meant "I was getting the bejeezus beaten out of me, and it hurt like the dickens".
Which begs the question why a horn player in mid-60s Las Vegas being shown yet again that loan sharks have no patience should be a member of a compendium about spies. Well, that sort of gets explained a bit into the first recorded adventure when Callaway runs into an old acquaintance from Indiana University named Ken and Ken has some trouble with the secret facility where he works and needs a bit of help and, hey, it was Ken who knew a guy who knew a guy and that is how Callaway ended up in Vegas playing at the Copa so he kind of owes Ken a lot.
What Callaway did not know was that the kind of problem Ken was dealing with and which Callaway sort of get mixed up in would also very much involve the CIA and once those fellows know about you and know that you can be pretty flexible where you work as long as the music is flowing and so is the money, well, they kind of never forget you.
