First Litvinenko now Kovtun?

It looks like the Russians might be knocking their critics off one by one.

Dmitry Kovtun, a contact of dead Russian ex-spy Alexander Litvinenko, is in
critical condition in hospital from radiation poisoning, Interfax news agency
quoted an unnamed source as saying on Thursday.

It also doesn't pay to talk to investigators into Litvinenko as well.

Interfax also reported that Kovtun fell into a coma after British and
Russian investigators working on the Litvinenko case had finished questioning
him in a Moscow hospital. However, it gave no source for the information on a
coma.

I keep getting a picture in my head of Rosa Klebb firing a hidden polonium 210 bullet into Litvinenko from her shoe while doing the bidding of SMERSH.
