"Umm, no," the sandy-haired man relieved the colonel. "There's absolutely no evidence to support it, and scientists don't accept unsupported assumptions unless they need them to explain something, and they don't need this assumption for anything. Well, it would come in handy to make some of these reports of freak phenomena, like mysterious appearances and disappearances, or flying-object sightings, or reported falls of non-meteoric matter, theoretically respectable. Reports like that usually get the ignore-and-forget treatment, now."
"Zen you believe zat zeese ozzer world of zee alternate probabeelitay, zey exist?"
"No. I don't disbelieve it, either. I've no reason to, one way or another." He studied his drink for a moment, and lowered the level in the glass slightly. "I've said that once in a while things get reported that look as though such other worlds, in another time-dimension, may exist. There have been whole books published by people who collect stories like that. I must say that academic science isn't very hospitable to them."
"You mean, zings sometimes, 'ow-you-say, leak in from one of zees ozzer worlds? Zat has been known to 'appen?"
"Things have been said to have happened that might, if true, be cases of things leaking through from another time world," the sandy-haired man corrected. "Or leaking away to another time world." He mentioned a few of the more famous cases of unexplained mysteries—the English diplomat in Prussia who vanished in plain sight of a number of people, the ship found completely deserted by her crew, the lifeboats all in place; stories like that. "And there's this rash of alleged sightings of unidentified flying objects. I'd sooner believe that they came from another dimension than from another planet. But, as far as I know, nobody's seriously advanced this other-time-dimension theory to explain them."
"I think the idea's familiar enough, though, that we can use it as an explanation, or pseudo-explanation, for the program," the television man said. "Fact is, we aren't married to this Crossroads title, yet; we could just as easily all it Fifth Dimension. That would lead the public, to expect something out of the normal before the show started."
That got the conversation back onto the show, and we talked for some time about it, each of us suggesting possibilities. The stranger even suggested one—that the Civil War had started during the Jackson Administration. Fortunately, nobody else noticed that. Finally, a porter came through and inquired if any of us were getting off at Harrisburg, saying that we would be getting in in five minutes.
The stranger finished his drink hastily and got up, saying that he would have to get his luggage. He told us how much he had enjoyed the conversation, and then followed the porter toward the rear of the train. After he had gone out, the TV man chuckled.
"Was that one an oddball!" he exclaimed. "Where the hell do you suppose he got that suit?"
