This is not the Brothers Karamzov or The Idiot, but it is still very good nonetheless. Dostoevsky dealt with some pretty advanced psychological issues in this novel, which is essentially a cat-and-mouse game between the two primary characters, Velchaninov and Trusotsky. One of the characters had maintained a sexual relationship with the wife of the other, raising two issues: 1) Who is the father of the young daughter that was conceived during this relationship, and 2) Exactly how much doesthe slighted spouse know?
The plot is good, but the characters are really what make this novel intriguing. Velchaninov, to me, is reflective of a cross between Raskolnikov (from Crime and Punishment) and Stavrogin (from The Possessed). He is in some ways a nihilist, and he often fails to account for the effect that his actions will have on others. Trusotsky, on the other hand, is a unique, baffling character. While the novel makes him largely come across as a buffoon, the final chapter suggests that Trusotsky is more cunning that the reader is initially led to believe.
For readers hoping to start with Dostoevsky, I would recommend The Idiot, as it is more representative of the traditional "Dostoevsky masterpiece." For a Dostoevsky fan looking for a quick fix, however, this is serviceable and entertaining.
