I think thank-you and IOU is also due to Sanjib, who shared his PustakVandar of "anubad series", "sharadias" with me. I cannot explain how much I loved those books then and how much I love them now.
Update on 11 November 2011:
I re-read 4-5 stories from the detective series. They are pretty good compared to the contemporary detective stories (Mitin, Arjun etc.) So apart from nostalgic values, they have their own place even in today.
