Publisher's Synopsis
My unfortunate friend P. has lost the thread of his life by the interposition of long intervals of partially disordered reason. The past and present are jumbled together in his mind in a manner often productive of curious results, and which will be better understood after the perusal of the following letter than from any description that I could give. The poor fellow, without once stirring from the little whitewashed, iron-grated room to which he alludes in his first paragraph, is nevertheless a great traveller, and meets in his wanderings a variety of personages who have long ceased to be visible to any eye save his own. In my opinion, all this is not so much a delusion as a partly wilful and partly involuntary sport of the imagination, to which his disease has imparted such morbid energy that he beholds these spectral scenes and characters with no less distinctness than a play upon the stage, and with somewhat more of illusive credence. Many of his letters are in my possession, some based upon the same vagary as the present one, and others upon hypotheses not a whit short of it in absurdity.
