What is remarkable about the diary of Dostoevsky's wife for the history of his life and work, what facets of them does he reveal? The first two parts of the diary, which describes the arrival abroad, the life of the Dostoevsky in Dresden and Baden, as well as a visit to Basel on the way to Switzerland, as it was said, entered the literature about Dostoevsky more than half a century ago. For no other period of the writer's life is there such a detailed and chronologically reliable source. The first and almost his main feature, which is revealed by a careful reading of the diary, is the opportunity to more clearly imagine the ideological positions and state of mind of the writer in this first year abroad. This diary is not only a detailed account of every day of his life, but also a chronicle of his judgments made by him in passing, on private occasions, but in the generalized and almost always pointed, dramatized form that is characteristic of his letters. Writing in the diary the impressions of the day, A. G. Dostoevskaya is most often unable to distinguish her own opinion from what her husband said. His voice always sounds in assessments of the surrounding reality, social, artistic, literary phenomena scattered across the pages of the diary.
