Marma Desam debuted with 'Ragasiyam' - produced by KB & story by Indra Soundarajan and became a runaway hit amongst the TV audience. The concept of Ragasiyam was novel by Indian TV standards. Then came 'Vidadhu Karuppu' (a.k.a Vittuvidu Karuppa)
Ragasiyam was about the 'maragadha lingam' & 'siddhargal'. 'Vittuvidu...' is about the 'Karuppanasami' punishing all the baddies in the town. 'Yendira Paravai' (sorry eludes my memory now - *Thanks samy for correcting it*) was about 'Boomerangs'.
The hallmark of his stories are the delicate mix of mystery & mystique of super-human acts.
I liked Vittuvidu Karuppa very much. When i went to India this time around, I literally had to run from pillar to post to get a copy of the book. I went to a local used-book shop and picked up some other books by Indra and it did not fail to please me.
As spoken elsewhere, the use of 'fear' as deterrent has been a very commonly used approach to exert control/regulate the behavior of people.
Sometime in the future, planning to write more in detail about how 'fear' has figured in the scheme of things in man's social life for a long time.
BTB, the biggest drawback is his (yes, it is him) penchant for introducing totally irrelevant english passages, awefully bad english. (Well, am not a english supremacist, no-one necessarily demands him to write in English)
Having read 4 of his novels (including short stories) i will definitely feel comfortable buying/recommending mystery books by him
