Indra Soundar Rajan was an expert on South Indian
Hindu traditions and mythological lore. He was employed in
TVS Group of Companies before becoming a full-time writer. His stories typically deal with cases of supernatural occurrence, divine intervention, reincarnation, and ghosts; many stories foreground the conflict between rationalism, faith, and superstition. His stories are often based on or inspired by true stories reported from various locales around the state of
Tamil Nadu. Through most of the 1990s and 2000s, two or three of his "pocket novels" (about the length of a novella in English) were published every month in publications such as
Crime Story and
Today Crime News. Often, longer works were serialised over several issues. Several of his novels have been translated to English, including
The Aayakudi Murders,
Out of the Blue,
The Rebirth of Jeeva (in
The Blaft Anthology of Tamil Pulp Fiction, Vol. 1), and
The Palace of Kottaipuram (in
The Blaft Anthology of Tamil Pulp Fiction, Vol. 2). The teleserial
Marmadesam, for which he wrote the screenplay, is said to be the most successful Tamil television show in history. He wrote more than 300 episodes for the Podhigai TV program "Kanchiyin Karunai", which tells of the greatness of
Shri Chandrasekhara Saraswathi Swamigal, the pontiff of Kanchipuram Shankara mutt. ==Personal life and death==
