s unlike as night
and day--though there is no night and day proper upon Avis Solis, of
course. I imagine you would like to hear the story. Then you will
undoubtedly understand how it is that I was so upset a moment ago by the
sight of Avis Solis, and forgive me."

Mr. Wordsley nodded. A birdlike, snake-charmed nod.

"Avis Solis is a planet absolutely unique, at least in this galaxy. In
addition to being a solitaire, its surface is almost solidly covered to
a depth of several meters with light-gathering layers of crystal which
give it the brilliant, astral glow that you saw just now. Its satellite
suns contribute hardly any light at all. It contains ample oxygen in its
atmosphere, but hardly any water, and so is practically barren. An
ill-advised mineralogical expedition brought us to Avis Solis."

"Us?" Mr. Wordsley said.

"There were six of us, five men and a woman. A woman fine and loyal and
beautiful, with the body of a consummate goddess and the face of a
tolerant angel. I was astrological surveyor and party chief."

"I didn't know that you were once a surveyor."

"It was seventeen years ago, and none of your business besides."

"What happened then?"

"Briefly, we were prospecting for ragnite, which was in demand at the
time. We had already given up hopes of finding one gram of that mineral,
but decided to make a last foray before blasting off. My brother,
Malmsworth, stayed at our base camp. Poor Jenny--that was her
name--remained behind to care for Malmsworth's lame ankle."

Captain DeCastros was lost for several minutes in a bleak and desolate
valley of introspection wherein Mr. Wordsley dared not intrude. There
was a certain grandeur about his great, dark visage, his falciform nose
and meaty jowls as he stood there. Mr. Wordsley began to fidget and
clear his throat.

DeCastros glared at him. "They were gone when we returned. Gone, I tell
you! She, to her death. Malmsworth--well, we found _him_ three hours
later in the great rift which bisects the massive plateau that is the
most outstanding feature of the regular surface of Avis Solis. At the
end of this rift there is a natural cave that opens into the sheer wall
of the plateau. Within it is a bottomless chasm. It was here that we
found certain of Jenny's garments, but of Jenny, naturally, there was no
trace. He had seen to that."

"Terrible," Mr. Wordsley said.

DeCastros smiled reminiscently. "He fled,
