At first all was black around us, but as our eyes became accustomed to the darkness, we saw that a faint light filtered in from somewhere in the roof above our heads.

We could make out the pale blur of the white rock wall on one side and the merest glimmer of the pool below.
"No," Terry began, "he could have seen nothing; he must have--" He broke off suddenly and gripping my arm whispered out, "What's that ?" "Where ?" I asked.
"Up there; straight ahead." I looked up and saw two round eyes which glittered like a wild beast's, staring at us out of the darkness.

A cold chill ran up my back and I instinctively huddled closer to the others.

For a moment no one spoke and I heard the click of Terry's revolver as he cocked it.

Then it suddenly came over me what it was, and I cried out: "It's Cat-Eye Mose!" "Good Lord, he can see in the dark! Strike a light, some one," Terry said huskily.
The sheriff struck a match.
