I mounted, remembering how hurriedly Vertorix and I had gone up so many ages before, with the horde hissing and frothing at our heels. I found myself tense with dread as I approached the dark, gaping entrance through which the pack had sought to cut us off. I had snapped off the light when I came into the dim-lit corridor below, and now I glanced into the well of blackness which opened on the stair. And with a cry I started back, nearly losing my footing on the worn steps. Sweating in the semidarkness I switched on the light and directed its beam into the cryptic opening, revolver in hand.
