'It’s so difficult to remember what order things occurred in – but if you can’t remember that, then it’s impossible to work out which led to which, and what the connection was. What I remember, when I examine my memory carefully, isn’t a narrative at all. It’s a collection of vivid particulars. Certain words spoken, certain objects glimpsed. Certain gestures and expressions. Certain moods, certain weathers, certain times of day and states of light. Certain individual moments, which seem to mean so much, but which mean in fact so little until the hidden links between them have been found.' Quoted from Spies by Michael Frayn, Faber & Faber, Pbk 2003.
