not
comment. He brought out cards and showed her a complicated game of
solitaire in which mental arithmetic and expert use of probability
increased one's chance of winning.

By midnight, ship-time, she'd learned the game and played it absorbedly.
Calhoun was able to scrutinize her without appearing to do so, and he
was satisfied again. When he mentioned that the Med Ship should arrive
off Dara in eight hours more, she put the cards away and went into the
other cabin.

Calhoun wrote up the log. He added the notes that Maril had made for
him, of Murgatroyd's pulse and blood-pressure after the injection of the
same culture that produced fever and thirstiness in himself and
later--without contact with him or the culture--in Maril. He put a
professional comment at the end.

"The culture seems to have retained its normal characteristics during
long storage in the spore state. It revived and reproduced rapidly. I
injected .5 cc under my skin and in less than one hour my temperature
was 30.8 deg.C. An hour later it was 30.9 deg.C. This was its peak. It
immediately returned to normal. The only other observable symptom was
slightly increased thirst. Blood-pressure and pulse remained normal. The
other person in the Med Ship displayed the same symptoms, in prompt and
complete repetition, without physical contact."

He went to sleep, with Murgatroyd curled up in his cubbyhole.

The Med Ship broke out of overdrive at 1300 hours, ship time. Calhoun
made contact with the grid and was promptly lowered to the ground.

It was almost two hours later--1500 hours ship-time--when the people of
Dara were informed by broadcast that Calhoun was publicly to be
executed; immediately.

CHAPTER 7

From the viewpoint of Darians, the decision of Calhoun's guilt and the
decision to execute him were reasonable enough. Maril protested
fiercely, and her testimony agreed with Calhoun's in every respect, but
from a blueskin viewpoint their own statements were damning.

Calhoun had taken four young astrogators to space. They were the only
semi-skilled space-pilots Dara had. There were no fully qualified men.
Calhoun had asked for them, and taken them out to emptiness, and there
he had instructed them in modern guidance-methods for ships of space. So
far there was no disagreement. He'd proposed to make them more competent
pilots; more capable of driving a ship to Orede, for example, to raid
the enormous cattle-herds there. And he'd had the
