This is India and every promoter will have some skeletons in their closets.
I recently read this book and Diamonds in the Dust by Saurabh.
Being an active investor, I can vouch for its content. Diamonds in the dust is essential reading if you invest in stocks directly in my opinion.
If for the simple reason that the good perfomers of a decade ago may be poor performers and may not even be around today.
