THE POLONIUM MYSTERY DEEPENS: first, seven employees of the Millenium Hotel in London have tested positive for radiation.

And second and more intriguing, just in: Dmitry Kovtun, a businessman and ex-spy like Litvinenko and who met him in London just after he fell ill, has entered into a coma after being interrogated by Russian investigators and Scotland Yard officers.

This is becoming more and more like a cheap paperback.
