Telescopes were trained on the eccentric planet early the next morning. Its reddish appearance was due, Ezra Keroon suggested, to the aggregated dust swirls it had brought in from the edge of the system. Despite the lack of any proof, the feeling among the observers was that the planet was somehow responsible for the disaster.

During the day, Kenjo’s group discovered traces of an earlier fall on Ierne Island, which a witness remembered as more of a rainstorm littered with black motes than a fall of Thread. A scout sent to the northern continent reported traces of recent destruction across the eastern peninsula there. That discovery dispersed the vain hope that the Fall was unique or confined to a specific area. A review of the probe pics from the EEC did nothing to alleviate tension, for the fax incontrovertibly showed the Fall two hundred years before to have been widespread. They figured that the event must have happened just prior to the team’s arrival. The demand to know the extent and frequency of the falls increased ominously.

To assuage mounting fears and tension, Betty Musgrave-Blake and Bill Duff undertook to review the survey’s original botanical data. Ted Tubberman was the only trained botanist who had survived, but he spent his days tracking down every Thread shell and his evenings burning the piles. The psychologists continued to monitor his aberrant behavior.

Based on the original data, Betty and Bill deduced a two-hundred-year gap between incursions, allowing a span of ten to fifteen years for the vegetation to regenerate on the damaged circles after taking into account the age of some of the largest trees in and near the previous occurrence. Betty delivered their conclusion as a positive statement, meant to engender optimism, but she could provide no answer to the vital question of how long the deadly rain would continue to fall.

In an attempt to disprove Mar’s theory of purposeful design or Phas’s equally disturbing suggestion of invasion, Ezra Keroon spent that day on the link with the Yokohama’s mainframe. His calculations confirmed beyond question that the eccentric planet had an orbit of 250 years. But it only stayed in the inner system for a little while, the way Halley’s comet periodically visited Sol. It was too much to suppose there was no connection, and, after consulting Paul and Emily, Ezra programmed one of the Yokohama’s few remaining probes to circumnavigate the planet and discover its composition and, especially, the components of its apparently gaseous envelope.

Though all reports were honestly and fully presented to the community as soon they came in, by evening speculation had produced alarming interpretations. Grimly the more responsible members tried to calm those who gave way to panic.

Then a perplexed Kenjo sought Betty out with a disturbing observation. She immediately informed Paul and Emily, and a quiet meeting was arranged with those who were able to discuss the situation with some detachment.
