Aglaya Terekhova

Yakov Ivanych's sister, a tall, gaunt old woman rumored to have secretly remained a Khlyst since her youth despite outwardly praying alongside her brother; sharp-tongued and spiteful outside the prayer-room but meek and softened within it, she strikes the fatal first blow against Matvei with a bottle of Lenten oil and is sentenced to thirteen and a half years' penal servitude.
