Note 3 — Chapter IV · THE OSTROG AT OMSK
Reading edition
In the latter part of his book Dostoyevski corrects this early account of the supposed parricide, and tells us that it was all a mistake. It was a grave case of judicial error. The convict, when he had served ten years’ imprisonment, was proved to be entirely innocent. When the real murderers had been discovered and had confessed their crime, the wronged man was set at liberty.
