 What lie does Gwayne plan to tell the crew?
Captain Gwayne cursed and rolled over, reaching for his boots. Gwayne swore softly to himself. The two he'd drawn, Kaufman and Pinelli, seemed to be totally devoid of any sense of caution. But something had happened to the exploration party fifteen years back, and to the more recent ship under Hennessy that was sent to check up. Even the deep gorge where they'd found Hennessy's carefully buried ship was completely hidden by the fog. Earth had ordered him to detour here, after leaving his load of deep-sleep stored colonists on Official World 71, to check on any sign of Hennessy. One, at the front, was stuttering into life, and Gwayne dashed for it as the exit port slid back.
 Everyone is already infected.
 There is not enough fuel to get back to Earth.  The ship is broken.  Earth no longer exists.  Everyone is already infected.
