"Pithead Control calling Dr. V. Hunt. Dr. Hunt, come in, please." The sudden voice in his helmet startled him. He pressed a button in the control panel on his chest.

"Hunt answering," he acknowledged. "I hear you."

"Routine check. You're five minutes overdue to report. Is everything okay?"

"Sorry, didn't notice the time. Yes, everything's okay . . . very okay. I'm coming back now."

"Thank you." The voice cut off with a click.

Had he been gone that long? He realized that he was cold. The icy fingers of the Ganymedean night were beginning to feel their way inside his suit. He wound his heating control up a turn and flexed his arms. Before he turned, he looked up once more for a final glimpse of the giant planet. For some strange reason it seemed to be smiling.

"Thanks, pal," he murmured with a wink. "Maybe I'll be able to do something for you someday."

With that he began moving down from the ridge, and rapidly faded into the sea of cloud.

Chapter Twenty-Three

A group of about thirty people, mainly scientists, engineers, and UNSA executives, filed into the conference theater in the Navcomms Headquarters building. The room was arranged in ascending tiers of seats that faced a large blank screen at the far end from the double doors. Caldwell was standing on a raised platform in front of the screen, watching as the various groups and individuals found seats. Soon everybody was settled and an usher at the rear signaled that the corridor outside was empty. Caldwell nodded in acknowledgment, raised his hand for silence, and stepped a pace forward to the microphone in front of him.

"Your attention, please, ladies and gentlemen . . . Could we have quiet, please . . ." The baritone voice boomed out of the loudspeakers around the walls. The murmurs subsided.

"Thank you all for coming on such short notice," he resumed. "All of you have been engaged for some time now in some aspect or other of the Lunarian problem. Ever since this thing first started, there have been more than a few arguments and differences of opinions, as you all know. Taking all things into consideration, however, we haven't done too badly. We started out with a body and a few scraps of paper, and from them we reconstructed a whole world. But there are still some fundamental questions that have remained unanswered right up to this day. I'm sure there's no need for me to recap them for the benefit of anyone here." He paused. "At last, it appears, we may have answers to those questions. The new developments that cause me to say this are so unexpected that I feel it appropriate to call you all together to let you see for yourselves what I saw for the first time only a few hours ago." He waited again and allowed the mood of the gathering to move from one suited to preliminary remarks to something more in tune with the serious business about to begin.
