Suggestions on Indian Books and Authors!

Kindly suggest me some good Indian Books and some good Indian authors as well from the following genres ONLY:-

Psychological

Thriller

Suspense

Crime

Mystery

Horror (is acceptable as well)

I don't read romance, fantasy and any other genres other than the above mentioned! I do read non-fiction but only when it's about PSYCHOLOGY! In this case avoiding to mention any Non-fiction books would be appreciable!

Also I would like to add the books I have read to to make you understand my reading taste—My first Indian book was Suzanna's Seven Husbands by Ruskin Bond and my 2nd and the last Indian book was That Night by Nidhi Upadhyay! I like sticking to my fav genres!
