ready they are subject to mass neurosis because they cannot
adjust to a world that changes too quickly."

"I wonder if that doesn't apply to the rest of us as well," Cliff said
unhappily. "But the changes go on, if we like them or not. Can you
think of any way to turn them off?"

The doctor snorted.

Homer Crawford said, "Dr. Smythe, the die is already cast. The
question now becomes, will you join us?"

"Join you! Certainly not!"

Crawford said evenly, "Then I might suggest that, first, you will not
be allowed to operate in my territory." He considered for a moment,

will prepare a desert feast suitable to the high esteem in which we

They looked after the doctor, as he left, and Moroka chuckled.
However, Isobel was watching Homer Crawford quizzically.

She said finally, "We rode over him a little in the roughshod manner,

Homer Crawford growled uncomfortably, "Particularly when we finally
have our showdown with the Arab Legion, a medic will be priceless."

Isobel said softly, "And the end justifies the means--"

Homer shot a quick, impatient look at her. "The good doctor and his
