Of the motley line of half-timbered houses that stretched along the southern verge of the Parade, the Lieutenant’s Lodging lay farthest to the west. The one Rufus MacIan was concerned with was at the opposite, easternmost end, therefore closest to Bloody Tower. It was thrust out into the green in a manner that, to the military eye, recalled a bastion. Between its eastern face and Bloody Tower was an open ground perhaps fifteen yards across—a narrow enough interval to allow for targeted musket-fire. In other words, Guards barricaded in that house could spoil their plans vis-à-vis Bloody Tower.
