The Untouchable

ACKNOWLEDGEMENTS

Very many books have been written on the subject of the Cambridge spies; the majority of these I have not read.

However, the following three have been of great help to me:

Conspiracy of Silence, by Barrie Penrose and Simon Freeman (Grafton, London, 1986)

Mask of Treachery, by John Costello (William Morrow and Company, New York, 1988)

My Five Cambridge Friends, by Yuri Modin (Headline, London, 1994)

I should also mention:

Code Breakers: The Inside Story of Bletchley Park, edited by F. H. Hinsley and Alan Stripp (Oxford University Press, Oxford, 1993)

London at War 1939-1945, by Philip Ziegler (Sinclair-Stevenson, London, 1995)

Louis MacNeice, by Jon Stallworthy (Faber & Faber, London, 1995)

Poussin, by Anthony Blunt (Pallas Athene, London [reprint], 1995)

Karl Marx, by Isaiah Berlin (Thornton Butterworth, London, 1939)
