never been any absolute, theoretical objections to a temporal displacement of this magnitude . . . or any
magnitude, for that matter. The limiting factors have been political and economic. We have, with great
difficulty, obtained authorization for this expedition. It helps that this project lacks the . . . sensitive
aspects of some of our other proposals involving the distant past."
"Right. I remember how you had to quietly drop the idea of an expedition to Jerusalem in the spring of 30
A.D."
"Indeed." Rutherford shuddered at the recollection. "At the same time, the event in question is one of the
most important in human history, and one whose effects are still very much in dispute."
Jason nodded unconsciously. One of the justifications for time travel's hideous expense was the resolution
of historical controversies and mysteries. Written records tended to be incomplete, biased, self-serving or
downright mendacious. Only direct observation could reveal the truth behind the veil of lies, myths,
defamation and propaganda. Already, only half a century after its invention, the Fujiwara-Weintraub
Temporal Displacer had forced historians to rethink much of what they had thought they'd known. And,
in the process, the investigators had been able to establish a trade in items from the past that was so
lucrative it helped defray the cost.
Of course, Jason reflected, they often keep some of the choicest items for themselves. He glanced at
the display case behind Rutherford's desk. A sword caught his eye: a standard-issue early nineteenth
century dragoon saber, somewhat the worse for wear and utterly undistinguished save for the fact that on
a March day in 1836 a certain William Barrett Travis, colonel by dubious virtue of a commission from an
arguably illegal insurrectionist government, had used it to draw a line in the dust of an old Spanish
mission's courtyard in San Antonio, Texas, North America. . . .
Jason dragged his mind back to the matter at hand. "You still haven't explained why you need me, in
particular. I'm not the only one with my qualifications. Almost," he added, because it seemed a shame not
to live down to Rutherford's expectations, "but not quite."
"Two reasons. The first is the perennial problem of physical inconspicuousness. Of all the available
persons with your qualifications—fairly rare ones, as you have indicated with your characteristic
modesty—we feel you are the one with the best chance of passing unremarked in the target milieu."
"Probably true," Jason grudgingly conceded. Most of Earth, for most of its history, had not been as
ethnically cosmopolitan as it had become since the Industrial Revolution. A blond, blue-eyed European in
Ming Dynasty China, or an obvious African in Peter the Great's Russia, would have some explaining to
do. In theory, the capability to alter physical appearances by nanotechnological resequencing of the
genetic code had existed for centuries. But the crazy excesses of the Transhuman movement before its
bloody suppression had placed that sort of thing beyond the pale of acceptability. The Service had to
