that pen. She wasn't in danger; there was no reason to shoot her-"
"Wrong," said Dr. Obama. "Wrong, twice over. You should know that."
"I shouldn't know anything!" I said, suddenly angry. "I've never been told anything. I was transferred up
here from a reclamation unit because somebody found out I had two years of college-level biology.
Somebody else gave me a uniform and a rule book-and that's the extent of my training."
Dr. Obama looked startled, resigned and frustrated, all at once. Almost to herself-but loud enough so I
could hear it too-she said, "What the hell are they doing anyway? Sending me kids. . . ."
I was still burning. "Duke should have shot at the Chtorr!" I insisted.
"With what?" Dr. Obama snapped back. "Were you packing artillery?"
"We had a high-powered rifle-"
"And the range to the Chtorr was more than seven hundred meters on a windy day!"
I mumbled something about hydrostatic shock. "What was that?"
"Hydrostatic shock. It's what happens when a bullet hits flesh. It makes a shock wave. The cells are like
little water balloons. They rupture. That's what kills you, not the hole."
Dr. Obama stopped, took a breath. I could see she was forcing herself to be patient. "I know about
hydrostatic shock. It doesn't apply here. You're making the assumption that Chtorran flesh is like human
flesh. It isn't. Even if Duke had been firing point blank, it wouldn't have done any good unless he was
lucky enough to hit one of their eyes-or unless he had an exploding cartiidge, which he didn't. So he had
no choice; he had to shoot what he could." Dr. Obama stopped. She lowered her voice. "Look, son, I'm
sorry that you had to come up against the harsh realities of this war so quickly, but-" She raised her
hands in an apologetic half-shrug, half-sigh, then dropped them again. "-Well, I'm sorry, that's all."
She continued softly, "We don't know what the Chtorr are like inside-that's why we want you here.
You're supposed to be a scientist. We're hoping you'll tell us. The Chtorr seem to be pretty well armored
or segmented or something. Bullets don't have much effect on them-and a lot of good men died finding
that out. Either they don't penetrate the same way, or the Chtorrans don't have vital organs that a bullet
can disrupt-and don't ask me to explain how that one's possible, because I don't know either. I'm just
quoting from the reports.
"We do know, though-from unfortunate experience-that to shoot at a Chtorran is to commit suicide.
Whether they're intelligent or not-as some people think-makes no difference. They're very deadly. Even
without weapons. They move fast and they kill furiously. The smartest thing to do is not to shoot at them
at all.
"Duke wanted to rescue that child-probably more than you realize-because he knew what the alternative
to rescue was. But when Louis saw Chtorr in the woods, Duke had no choice-he didn't dare go after her
then. They'd have read him halfway down the hill. He'd have been dead before he moved ten meters.
Probably the rest of you too. I don't like it either, but what he did was a mercy.
"That's why he passed the binoculars; he wanted to be sure he wasn't making a mistake-he wanted you
and Shorty and Larry to double-check him. If there was the slightest bit of doubt in any of your minds, he
wouldn't have done what he did; he wouldn't have had to-and if I thought Duke had killed that child
unnecessarily, I'd have him in front of a firing squad so fast he wouldn't have time to change his
underwear."
I thought about that. For a long moment.
Dr. Obama waited expectantly. Her eyes were patient. I said, suddenly, "But Shorty never looked at
all."
She was surprised. "He didn't?"
"Only the first time," I replied. "He didn't look when we saw the child and he didn't look to confirm it was
Chtorr."
Dr. Obama grunted. She was writing something on a note pad. I was relieved to have her eyes off me
even for a moment. "Well, that's Shorty's prerogative. He's seen too many of these-" She finished the
note and looked at me again. "It was enough that he saw the enclosure. But it's you we're concerned with
at the moment. You have no doubt, do you, that what you saw was Chtorr?"
"I've never seen a Chtorran, ma'am. But I don't think this could have been anything else."
