In what 1842 Nikolai Gogol novel does the protagonist Chichikov travel across the Russian countryside to purchase the names of deceased serfs from landowners?

Dead Souls

The title refers to both the deceased serfs and the spiritual emptiness of the characters Chichikov encounters. Gogol intended the work to be the first part of a trilogy modeled after Dante's 'Divine Comedy,' but he burned the manuscript for the second part before his death.
