Prologue
Doctor McCoy picked up his rook and plunked it down again, taking one of his opponent’s pawns.
“Get out of that one if you can,” he said, sitting back confidently. The man on the other side of the
chessboard raised a quizzical eyebrow.
“An interesting move ...” Spock conceded, and lapsed into an unmoving study of the board.
McCoy smiled. Spock had agreed to a game of the old-fashioned, two-dimensional chess when the
Doctor suggested it. Now the Vulcan was discovering that McCoy’s moves, though occasionally erratic,
could be inspired, and a challenge to his logical mind. McCoy hadn’t been captain of the chess team in
med school for nothing.
While the First Officer mulled over his Queen’s predicament, McCoy glanced idly around the recreation
room. It was filled with crew members reading, playing cards or chess, or talking in groups. His gaze
stopped on the face of a pretty young Ensign. The Doctor searched his mind for her name, recalled it.
Teresa McNair. Straight out of the Academy, barely a day over twenty-three. Nice brown hair, green
eyes. She had her nose in a micro-reader, scanning the material with careful scrutiny. As he watched,
enjoying the long, slender legs curled up underneath her, she stopped the reader with a quick gesture and
sat up. Tearing off two long strips of readout paper, she got up and walked straight toward him.
McCoy gave a guilty start, realizing he’d been staring, and turned away. A moment later, McNair[14]
appeared at Spock’s elbow. “Excuse me, Mr. Spock.”
The First Officer looked up. “Yes, Ensign?”
“Sir, would you please confirm a fact for me? I thought it was well-established that early Vulcan
colonization was confined to the area closest to the Romulan Neutral Zone?” McNair’s voice rose,
making it a question.
“That’s correct, Ensign.” Spock was patience itself, but hardly inviting.
“Then do you know of any explanation for this?” She placed the large readout in front of the Vulcan and
continued, “This photo came from archeological data published about the Beta Niobe system. That’s
clear at the other end of the explored portion of the Galaxy, and if there was no Vulcan colonization ...”
McNair sounded puzzled as she trailed off.
McCoy saw something flicker across Spock’s face at the mention of Beta Niobe. He vainly tried to
place it ... no use, too many planets, too many suns. You had to be a biological computer like the Vulcan
to remember half of them.
Spock scanned the sheet, eyes narrowed. The Doctor looked up at McNair. “Beta Niobe? Can’t place
it, but it sounds familiar.”
The Ensign grinned at him and responded, “It should, Doctor. TheEnterprise was the ship detailed to
warn the people of Sarpeidon that Beta Niobe was ready to nova. I believe you were one of the landing
party. There was a huge library complex on the planet. Our computers scanned and recorded the
information in it before Sarpeidon was destroyed. The archeological information I was studying came
right out of the Atoz Library.” She turned back to Spock, who was still studying the readout. “Neutron
dating places the cave paintings you can see as circa 5,000 years old—Sarpeidon’s last ice age. This is
