A Middle-of-the-Road look at the Cambridge Five

From The Guardian, in review of The Enemies Within, by Trevor Louden:

In Davenport-Hines’s conclusion, the security services were neither “silly asses nor obtuse reactionaries” but decent public servants: “generally subtle, patient, responsive and astute, though never superhuman or infallible”. After a hundred years of spy writing not much has changed: those who step between the reflecting mirrors of British and Soviet intelligence generally have their heads turned.


If the needle has swung back to the middle, is there anything else to be said about the five?
