In a moment a figure loomed out of the darkness only a few feet away. Rick sucked in his breath and half lifted his rifle for a one-hand shot. At the same moment, he pressed the flashlight button.
The beam shot squarely into the face of Worthington Ko!
Rick put down his rifle quickly to extend a helping hand to the merchant. And then he noticed something.
Shoot a light into the eyes of a man whose pupils are dilated by darkness and there is a definite reaction. If the eyes are normal, the pupils contract sharply.
One of Ko's did. Rick saw them, magnified by the thick glasses. The other pupil didn't change at all.
And as the fact registered, Rick saw something else. In one of Ko's hands was a grenade!
In the instant that Rick grabbed up his rifle and swung it like a club, he guessed the answer.
Ko was the Chinese with the glass eye!
