"Well," said I to myself, "whatever else she may be, our angel is human."

We remained there for a little while, recovering from the effects of the horrible scene through which we had passed, then arose and started for that place of safety there amongst the wonderful, stupendous limestone pillars. I was now moving in advance, and I confess (and nothing could more plainly show how badly my nerves had been shaken) that I would gladly have covered those few remaining yards on all fours—if my pride would have permitted me to do so.

Yes, there we stood, by that very pillar behind which the angel had waited for us with her demon. There was her lamp, lantern rather, and dark, save for a mere slit.

I looked at it and looked all around.

"We saw two lights," I said. "And yet she was waiting for us here alone."

"There certainly were two lights, Bill; in other words, there certainly were two persons at least. Her companion went somewhere; that is the only explanation that I can think of."

"I wonder where," said I, "and what for."

"Help, in all likelihood. You know, Bill, I have an idea that, if we had delayed much longer, our reception there," and he waved a hand toward the bridge, "would have been a very different one."

"It was interesting enough to suit me. And, as it is, Heaven only knows what is to follow. This is, perhaps, just the beginning of things."

The angel, standing there straight and still, was watching us intently, so strange a look in her eyes—those eyes were blue—that a chill passed through my heated brain, and I actually began to wonder if I was being hypnotized. Hypnotized? And in this cursed spot.
