The planking led to a small opening in the sheer face of the Tower’s outer wall. On the right hand, a wedge-shaped bastion was thrust out from the same wall, but it offered no doorways: only embrasures and murder-holes from which defenders could shower fatal attentions upon people trying to get across this bridge. But tonight the drawbridge was down, the portcullis was up, no projectiles were spitting out of the orifices of the Tower. The group slowed down to file through a sort of postern gate into the base of Byward Tower.
