Moreover, Thomas Carlyle went to no little trouble to procure evidence when writing the history of Frederick the Great, that the "White Lady" had appeared to that famous monarch on the eve of his death. The king, it is asserted, was on the high road to recovery from his illness, when suddenly one morning he declared that he had seen the white-clad spectre during the night, that his hour had come, and that it was useless to ward off death any longer. So he refused to take any further medicine or nourishment, turned his face to the wall, and died. The "White Lady" is considered sufficiently real by the hard-headed matter-of-fact commanders of the Prussian army, to lead to their adopting special measures whenever her appearance is reported. The moment she is seen, the sentinels within and around the royal palace are at once doubled. The object of this is not so much to protect the royal family from harm, as to prevent the sentinels themselves from following the example of the two who shot themselves while on guard at the palace in the year 1888, one, shortly before the death of old Emperor William, the other, a few days before the demise of Emperor Frederick, the men in each case declaring before they expired that they had seen the "White Lady," their story being in a measure borne out by the fact that their faces even after death seemed to be distorted with terror. The appearances of the "White Lady" are kept as quiet as possible, the matter is never mentioned at court, save in whispers, and nothing concerning her is ever permitted to appear in print in the Berlin papers. This dread apparition that forebodes evil to the reigning house of Prussia, is supposed to be the spectre of Countess Agnes Orlamunde, who murdered her first husband, as well as her two children, who constituted an obstacle to her marriage with, one of the ancestors of the kaiser. The palace in which the spectre of this historic murderess appears is a huge and massive structure of grey stone, the walls of which are pierced by over one thousand windows, and which contains over six hundred rooms. Commenced four hundred and fifty years ago by one of the earliest electors of Brandenburg, it has been added to by each sovereign in turn, until it has attained its present enormous dimensions.
