A white mouse hung in midair, as though suspended in a transparent sea.

Dr. Emma Watson drifted toward it, slender-limbed and graceful as an underwater dancer, the curlicue strands of her dark brown hair splayed out in a ghostly halo. She grasped the mouse and slowly spun around to face the camera. She held up a syringe and needle.

The footage was over two years old, filmed aboard the shuttle Atlantis during STS 141, but it remained Gordon Obie's favorite PR film, which is why it was now playing on all the video monitors in NASA's Teague Auditorium. Who wouldn't enjoy watching Emma Watson? She was quick and lithe, and she possessed what one could only call sparkle, with the fire of curiosity in her eyes.

From the tiny scar over her eyebrow, to the slightly chipped front tooth a souvenir, he'd heard, of reckless skiing) her face was record of an exuberant life. But to Gordon, her primary appeal her intelligence. Her competence. He had been following Emma's NASA career with an interest that had nothing to do with the fact she was an attractive woman.

As director of Flight Crew Operations, Gordon Obie wielded considerable power over crew selection, and he strove to maintain a safe -- some would call it heartless -- emotional distance from all his astronauts. He had been an astronaut himself, twice a shuttle commander, and even then he'd been known as the Sphinx, an aloof and mysterious man not given to small talk. He was comfortable with his own silence and relative anonymity.

Although he was now sitting onstage with an array of NASA officials, most of the people in the audience did not know who Gordon Obie was. He was here merely for set decoration. Just as the footage of Emma Watson was set decoration, an attractive face to hold the audience's interest.

The video suddenly ended, replaced on the screen with the NASA logo, affectionately known as the meatball, a star-spangled blue circle embellished with an orbital ellipse and a forked slash red.
