The rape exploded in Mary’s mind again, with a vividness that she hadn’t felt for weeks. Cornelius Ruskin’s cold blue eyes visible behind the black ski mask, the stench of cigarettes on his breath, his arm pushing her back against that retaining wall.
God damn Cornelius Ruskin.
God damn Jock Krieger.
Damn them both to hell.
Damn men to hell.
Only men would create something like the Wipeout virus. Only men would do something so heinous, so abominable.
Mary snorted. There weren’t even proper words left for such evil. “Heinous” had been robbed of its power by Keanu Reeves using it in Bill & Ted’s Excellent Adventure, and “abominable” was almost always followed by “snowman,” as if such evil could only exist in the realm of myth.
She’d always associate such evil with this world, the world of Genghis Khan and Adolf Hitler and Pol Pot and Paul Bernardo and Osama bin Laden.
And Jock Krieger.
And Cornelius Ruskin.
A world of men.
No, not just of men. A very specific kind of man. Male Homo sapiens.
Mary took a deep breath, calming herself. Not all men were evil. She knew that. She really did. There was her dad, and her brothers, and Reuben Montego, and Fathers Caldicott and Belfontaine.
And Phil Donahue and Pierre Trudeau and Ralph Nader and Bill Cosby.
And the Dalai Lama and Mahatma Gandhi and Martin Luther King, Jr.
Compassionate men, admirable men. Yes, there were some.
Mary had no idea how to distinguish genetically between great men and evil ones, between visionaries and psychopaths. But there was one glaring genetic marker for male violence: the Y chromosome. Granted, not everyone who had a Y chromosome was an evil man; indeed, the vast majority weren’t. But every evil man, by definition, had to have a Y chromosome, the shortest of all Homo sapiens chromosomes and yet the one that had the biggest impact on psychology.
And history.
And the safety of women and children.
Cornelius Ruskin had a Y.
Jock Krieger likewise.
Y.
Why?
No. No, it was too much. It really was too redolent of playing God.
But she could do it. Oh, she’d never dream of unleashing such a thing here, in this world. She was no murderer—that much of her own personal code of ethics Mary was certain of, for the man she hated most, the man she most wanted to see punished, was Cornelius Ruskin, and when Ponter had proposed killing him, Mary had insisted he not do it.
And, despite Adikor’s suggestion, Mary was sure Jock Krieger never meant for his Wipeout virus to be introduced to this version of Earth. It was doubtless intended for the other version, the Neanderthal world, a serpent for the un-spoiled Eden.
Of course, if everything went as planned, if she managed to stop Jock, no virus would be released in the Neanderthal world.
But if one was to be, well, hopefully it would be Mary’s Surfer Joe, either in the version she’d just produced, which did nothing, or…
Or…
She could make a more radical revision, producing a version that modified the original logic to act only if—
It was simple, so simple.
A version that would act only if the host cell the virus had invaded did not belong to a Neanderthal, and did contain a Y chromosome.
If, and only if…
Mary frowned. A revised Surfer Joe.
A Mark II—just like the new Pope, taking it all one step further.
She shook her head. It was madness. Sinful.
Or was it? She’d be protecting an entire world from male Homo sapiens. After all, if she and the paleoanthropologists who shared her view were right, it had been male Homo sapiens —the hunters in the clan, not the gatherers, not the women—who had slaughtered their browridged cousins here until not a single one was left.
And now, using the tools of the twenty-first century and technology borrowed from the Barasts themselves, male Homo sapiens were preparing to do again what male H. sap had done once before.
Mary looked at Jock’s computer screen.
It would be so simple. So very simple. The logic tree was already in place. She only needed to change the sequences being tested for, and which way the logic branched.
Testing for a Y chromosome was easy enough: just pick a gene from the Human Genome Project database that appeared only on that chromosome. Mary rummaged on Jock’s desk for pen and paper, then wrote out the logic in longhand on a yellow ruled pad:
Step 1: Is a Y chromosome present?
If yes, this is a male: go to Step 2
If no, abort (this isn’t a male)
Step 2: Is Gene ALPHA found next to a telomere?
If yes, abort (this is a Neanderthal)
If no, this is probably a Gliksin: go to Step 3
Step 3: Is Gene BETA found next to a telomere?
If yes, abort (this should never happen in a Gliksin)
If no, this is definitely a Gliksin: go to Step 4
Mary looked at what she’d written over and over again, but couldn’t find a flaw. There was no point at which the logic could get caught in an infinite loop, and there were not one but two checks to make sure she was really dealing with a Homo sapiens male and not a Homo neanderthalensis one.
Of course, it was all moot—surely Jock would be stopped before he could release his virus. Modifying it now was just a safeguard, in case somehow it made it over to the other side.
Mary shook her head and looked at her watch. It was well after midnight—the start of a new day.
She should just go home now. Jock’s Wipeout virus had been defused; it would do nothing at all, assuming, as Mary fervently hoped, that he hadn’t yet used the codon writer to output the actual viral molecules. Surfer Joe would harm no one. That’s all she’d set out to accomplish, after all.
That’s all that needed to be done.
And yet…
And yet.
No one would have to get hurt. She’d find a way to disseminate the information, to make sure that everyone on this Earth knew that it was unsafe for male Gliksins to travel to the Neanderthal world. The Barast tuned-laser decontamination technology would make sure the Surfer Joe virus never got back across the portal to this world. Male Gliksins—the majority that were decent, and the horrible minority that did so very much harm—would be safe, just as long as they left Ponter’s world the hell alone.
Mary took a deep breath, then let it out slowly.
She folded her hands in her lap, the left still showing the pale indentation on the third finger where her wedding ring had once been.
And Mary Vaughan thought and thought and thought.
And at last she unfolded her hands.
And then, of course, she did the only thing she could do.
Chapter Thirty-eight
“And although someday we may also travel to Dargal—for that is what the Neanderthals named the red planet of their universe, the crimson beacon that beams down upon the continents of Durkanu, Podlar, Ranilass, Evsoy, Galasoy, and Nalkanu—we will leave that version of Mars as we find it. Truly, like so much in this new era we are now entering, we will have our cake and eat it, too…”
