Of all the SPOOKS books this one ,a fictional account of Harry Pearce's time in MI5, I thought would be the least interesting but I couldn't have been more wrong. It's been a long time since I've read anything so eagerly and become fully absorbed in a fictional realm. Whilst it is a work of fiction it is very much based in real world events. I'm early/mid 40's in age and the beginning of this diary coincides with when I first became properly aware of politics and current affairs. It is a tremendous trip down memory lane with many of the events I remember (Falklands War, Brighton Bombing,Diana's death) with a sprinkling of some I don't or had just forgotten.For those I do readily recall, this gives a different perspective and insight on the media accounts of the day. I finished this book with a lot more understanding, respect and admiration for a fictional but very credible and realistic character in a television programme.For me this is the best of the SPOOKS books so far and I look forward to the next one, The Contingent Event Committee due to be published next year.
