What is the name of the character in Dostoevsky's 'Demons' who leads a secret revolutionary cell?

The character who leads the secret revolutionary cell in Dostoevsky’s “Demons” is Pyotr Verkhovensky.

Pyotr Stepanovich Verkhovensky is the novel’s principal political agitator and the driving force behind its campaign of conspiracy and violence. He claims links to a vast revolutionary organization and persuades a small local group that it is one cell in a nationwide movement. In reality, he relies heavily on manipulation, theatricality, and invented authority.

Verkhovensky’s revolutionary methods are associated with Sergey Nechayev, whose 1869 “Catechism of a Revolutionary” advocated total commitment and the deliberate use of disorder. Dostoevsky also drew on the real Nechayev affair, including the murder of student Ivanov by members of a revolutionary group. In the novel, Verkhovensky engineers the murder of Ivan Shatov to bind the conspirators together through shared guilt.

The other options play important roles but do not lead the cell. Shatov becomes its intended victim, Kirillov is an engineer drawn into its plans for ideological reasons, and Nikolai Stavrogin is the charismatic figure Verkhovensky hopes to recruit as a future leader. “Demons” is also translated as “The Possessed” or “The Devils.”
