A talented fellow called Pinaki De designed the cover, producing several trial runs and bearing with my constant back-and-forthing with plenty of good humour. I owe him plenty for what I think is a superb effort. He has the cover up on his blog here.
If you like it, please leave him a note saying so.
Incidentally, Pinaki lives in Chandannagar, which is one of the five once-French enclaves in this country (the French called it Chandernagore). I've been in three of them so far (Pondicherry, Karaikal and Mahe, fascinating places all), and Pinaki has promised to show me around Chandannagar. That will leave just one, Yanam (Yanaon to the French) in AP.
