A guy I met, got to know, and never knew

1956, Nevada Club, Reno Nevada. I was "turning out" as a dealer, very proud of myself, had my own little green apron, different world for me.
On the crap tables you worked 20 minutes at one end, 20 on the other, and a 20 minute break. So, spent some time in the really nice coffee shop/restaurant at Fitz's Nevada Club.
One customer, a man about 30, would stop by the table and chat, or maybe make a small bet or two. I trained and worked on the graveyard shift ... 3AM till 11, so there rarely were very big crowds, so we had time to chat.
This guy was sort of a "regular" so I got to know him a little. On occasions, when on a break, he would be eating, and if a vacant stool was nearby, would plop down and have a coffee with him.
He was interesting to talk with, had a wealth of knowledge about a world of subjects, much the same as I THOUGHT I had, so we hit it off pretty well.
Peculiar though, something, it was just peculiar.
Danny Fagan, who was my floor boss and a friend, saw me coming back from a break with him, and later came over t the table and made mention of it. Danny called me Kid, but he called everyone Kid. I will go more into Danny Fagan later, he also was interesting.
“Kid, you on a break with Jack there?”
“Yeh”
“Easy does it …. You know what I mean. Don’t ask anything, OK?
That was it, nothing more said.
We talked on breaks, had dinner once or twice, he came out the house for dinner a couple of times. Met my wife and daughter, he became a family member and friend, in a way.
I knew enough to not ask him what he did for a living, I did pick him up once at his apartment... nice building, out South, by the golf course, high rent area.
He was noticeable by his absence at times. Be gone for a week or so, and then pop up again. Never asked where he had been or anything like that, and there was rarely any information volunteered on where he had been.
But, I got to noticing that when he was gone, sometimes, somewhere, there would be an accident, or someone might get shot or something like that. Enough said? Just didn’t go in to details.
Conclusion. Our friend Jack, and that probably was not his real name, could have been …. Well, I found out later on that he actually was. I’ll just leave it at that.
He’s probably gone now, but I remember the last time we had him over to the house for dinner. We were leaving the next day to come back to Ohio. As he was leaving he said to me …. “If there is ever anything I can do for you ……..”
He was a very nice guy, quiet, educated, some self taught, originally from New Jersey. That explains some of it. Figures he was the West Coast branch of something. Lived quietly, played a lot of golf, always seemed to have ample money. Oddly enough, he was one of three …. Of that profession, that I met or knew in Nevada.
