Charles Fort attacked the very notion of categories. “But it is our expression that there are no positive differences: that all things are like a mouse and a bug in the heart of a cheese. Mouse and a bug: no two things could seem more unlike. They're there a week, or they stay there a month: both are then only transmutations of cheese. I think we're all bugs and mice, and are only different expressions of an all-inclusive cheese.”
No surprise, then, that when chasing down Forteans I’ve found they do not always have very much respect for one of the most common categories of our lives: names. That’s especially true of this Fortean. I’ll start by saying that he—it’s a he—was consistent with his surname: Markham. And, when he used it, his middle initial, G. (which probably stood for Garrett.) First name, though, was variously David or Norman. And that change made him difficult to track.
I think I figured it out. But let’s take it step by step.
