Sri Verahur Srinivasan, an ex-police IG, was a great devotee of Kanchi Paramacharya Sri Chandrasekarendra Saraswati and his spiritual experiences and also Paramcharya's Grace and Blessings on Sri Verahur Srinivasan is truly inspiring. Unfortunately none of the books authored by Sri Verahur Srinivasan seem to be available in the public domain or book stores.
I have got the Kindle edition which is Rs 161 as the hardcopy is a bit pricey at Rs 1500 plus.
