THREE years ago when Siddhartha Shankar Ray was appointed ambassador to Washington, few thought the septuagenarian would survive till the end of his term. Everything about him seemed wrong. He was too old and set in his ways. His cabinet status precluded him from interacting with lower ranking US officials.

And, most importantly, no one thought he could fit into Abid Hussain's shoes.
