The ship computer chimed softly and the emotionless voice began to speak to the silent crew. "Deflector
shield activation necessary in eight days, thirteen hours, and twenty-four minutes or radiation penetration
will exceed 100 rad."
"And that's enough to put half the crew down with radiation sickness," Kirk muttered.
"At the rate those curves peak," Helman said, nodding agreement with Kirk. "A few more hours'
exposure would kill us all, right?"
"Is a response required?" the computer asked.
"We aren't going to be here long enough to make the answer more than academic," Kirk said. "But as
long as you have one, let's hear it."
"Data indicates that, unless corrective measures are taken, all crew members, with one exception, will
receive a lethal dosage by twenty-three hundred hours, stardate 6728.5."
"Who might be the exception?" Kirk asked. "As if I couldn't guess."
"Commander Spock," said the computer. "Vulcans are twice as resistant to radiation as humans. If an
exact prediction of Commander Spock's resistance is desired, a tissue sample must be secured for
molecular analyzation."
"That figures," said a familiar voice sardonically. "While the rest of us are heaving and watching our hair
fall out, Spock and the computer will be playing three-dimensional chess."
Kirk swung his chair about.
"Bones," he asked, "what are you doing up here? I thought you had our sexpot in surgery."
Dr. McCoy laughed. "I had her on the table, just ready to give her a local when the yellow alert came
through. I thought I'd better report to the bridge to see if I was needed, so I told her to report back in the
morning. I imagine she's hanging around the transporter room on the odd chance she might get lucky
when Spock is beamed up."
He paused and gestured at the visual monitor dominating the front of the bridge.
"Looks like some nasty stuff is on the way in."
"'Nasty' is an understatement," the captain said. He gazed at the screen thoughtfully for a moment. "In
order to weather what will be coming in a few days from now, we'd have to put the shields up, and at the
rate that storm is peaking, we'd have to put them on maximum before too long. Twenty hours of that, and
the power reserves would be exhausted. If we didn't pull out before then, we'd fry. Buying a few more
hours would be pointless anyway. The transporters won't operate while the shields are up, and we've
already gathered all the data on Kyros that can be obtained from orbit. There's nothing urgent about the
survey, it's mainly a field test for the implants."
Kirk swung his command chair to his right. "Lieutenant Uhura, we're getting out of here. Open a channel
to Starfleet, give them our situation, and tell them we're leaving Kyros until things quiet down."
"Aye, sir," Uhura replied. She placed a hypertronic earphone in one ear and turned toward her console.
"In the meantime," Kirk was saying to McCoy, "Spock and his department can pin down the reason for
that intensity increasehellip;"
Suddenly, he was interrupted by an exclamation from the communications officer.
"Captain, I've lost contact with Starfleet," Uhura said. "I sent out the standard signal, but when I listened
for their recognition call, a blast of QRM nearly blew out my eardrum."
"Malfunction, Lieutenant?" Kirk asked.
"Checking now, sir," she replied. Hesitantly, she replaced the earphone and bent over her panel. After a
full five minutes of rapid checking, she straightened. "Negative, sir. Everything is in order, but there is
something interfering on the sub-space bands."
"That's impossible," Kirk said. "Helman, scan sub-space."
The tall science officer bent over his console and moments later snapped upright with a look of surprise.
"Computer!" he snapped, "check antenna and sensor circuits for malfunction." He swung toward Kirk
who had come out of his chair at Helman's order to the computer. "Captain, you won't believe thishellip;"
"All sub-space sensors fully operational," the computer said after a small pause.
"Put it on the main screen," Kirk ordered.
As Helman complied, it was Kirk's turn to feel surprise. The main screen showed a cloud-like formation,
