The mirror has cracked from side to side for Shashi Tharoor, that suave writer, diplomat, politician known for flicking back his hair and talking in a polished accent. He has walked, talked and tweeted his way out of many scandals and even a few scams in the past. But the strange case of the death of his third wife Sunanda Pushkar exactly a year ago seems set to stalk him. The dead do tell some tales, it seems. Now the police is acting on an autopsy report that suggests possible traces of a lethal poison called Polonium-210 in her body. After a great deal of confusion, we now know a year after the death that it’s not sparkling cyanide or a fit of rage that killed her but perhaps a poison we’ve heard of only in high-profile international murders. The case has certainly moved into the zone of mysteries that otherwise inhabit the world of fiction. It is Agatha Christieland out there in the case that swirls around Tharoor: beautiful women, dead beautiful woman, body in a lush hotel, a famous husband (him), suggestions of scandal and personal indiscretions, untraceable poison.
