Agnisakshi (meaning, With Fire As Witness) is a Malayalam novel written by Lalithambika Antharjanam.

It tells the story of a Nambudiri woman, who is drawn into the struggle for social and political emancipation but cannot easily shake off the chains of tradition that bind her.

Thethikutty (Devaki or Sumitarananda) is married to Unni Nambudiri of the well-known Brahmin family named Manampilly Illam.

In the novel, the author explores the ideas of choice, detachment, renunciation, love and devotion through three of her main characters - two women Thethikutty (Sumitarananda, Devaki Manampilli or Devi Bahen), Thankam Nair and one man Unni Nambudiri.
