SIR – Regarding the letter from Richard Bird on November 3. If Mr Bird gets hold of and reads the recent publication The Terminal Spy by Alan S Cowell (Broadway) he will get an insight into how these powerful people acquired their wealth.

The book looks at Alexander Litvinenko’s death and the players in that murder.

Also of interest is the complicity of various countries outside of Russia including Britain. Not pretty reading.
