"A cronocinese de Jonathan Hull", uma breve história de Anthony Boucher na sua Fergus O'Breen Series; publicado pela primeira vez em Ficção Científica Espantosa, Junho 1946, disponível no Internet Archive; reimpresso algumas vezes.
Um cara está vivendo para trás, talvez como resultado de algum cientista fazendo algo com ele.
Dois caras, na verdade; o cientista louco que construiu a máquina do tempo e seu assistente:
Givens did not notice my concern, but casually asked, "O.K. yet, M. S.?" He thought it humorous to call me "M. S.," which was, indeed, one of my degrees but which he insisted stood for Mad Scientist.
Whatever was wrong I would not find it out by staying there. Perhaps nothing whatsoever had happened. And yet that curious wrenching sensation surely indicated that the temporomagnetic field had had some effect.
I beckoned to Givens to follow me, and we stepped out of the machine. Two men were backing away from it in the distance. Their presence and their crablike retrograde motion worried me, and reminded me of those other two whom we had only glimpsed. To avoid them, we hastily slipped out the rear door, and into a world gone mad.
For a moment I had the absurd notion that some inconceivable error had catapulted us into the far distant future. Surely nothing else could account for a world in which men walked rapidly backwards along sidewalks and conversed in an unheard of gibberish.
But the buildings were those of 1971. The sleek atomic motorcars, despite their fantastic reverse motion, were the familiar 1972 models. I realized the enormity of our plight just as Tim Givens ejaculated, "M. S., everything's going backwards."
"Not everything," I said succinctly, and added none too grammatically, "Just us."
A parte que me lembro é que ele estava comendo comida entrando em uma mercearia e andando para trás, de modo que, para os observadores que avançavam, parecia que ele estava colocando coisas nas prateleiras. Comportamento estranho, claro, mas não é algo que alguém surte.
We had by now learned to walk backwards, so that we could move along the streets without exciting too much comment. Visualize this, and you will see that a man walking backwards from 12:00 to 11:55 looks like a man walking forwards from 11:55 to 12:00.
Visualize it further. A man moving in this wise who enters a store empty-handed at 12:00 and leaves loaded with food at 11:50 looks like a normal man who comes in with a full shopping bag at 11:50 and leaves without it at 12:00—a peculiar procedure, but not one to raise a cry of "Stop thief!"
