The not-so-reclusive Dame Stella Rimington, erstwhile head of MI5, made an excellent impression on my old friend Lord St John of Fawsley when he was chairman of the Royal Fine Art Commission, and Master of Emmanuel College, Cambridge. So much so that he recommended that she should succeed him. Alas it was not to be.
I cannot find any reference to this in her interesting autobiography, but I am told the Cambridge dons were worried that were she to occupy the Master's Lodge, it might become a terrorist target.
Perhaps they were right.
