A voice yelled excitedly, "Post Six! Post Six!" With a single leap the Sergeant was across the sill, and dropped silently to the ground.

Still blinded by the light he ran forward, jerking his revolver from the belt.

As he passed the corner of the barracks the sentry fired again, the red flash cleaving the night in an instant's ghastly vividness.

It revealed a woman shrinking against the yellow stone wall, lighted up her face, then plunged her again into obscurity.
The Sergeant caught the glimpse, half believing the vision a phantasy of the brain; he had seen her face, white, frightened, agonized, yet it could not have been real.

He tripped over the stone wall and half fell, but ran on, his mind in a turmoil, but certain some one was racing before him down the dark ravine.
