Small confession. If you throw the word 'spy' into the title of your novel, I am probably gonna read it. I have two sources for my obsession, neither of them are James Bond. Now, I love James, but I have never mistaken what 007 does for anything remotely resembling real tradecraft. TINKER, TAILOR, SOLDIER, SPY is about the zenith of fictional spy reality. If you have not seen the 6 hour miniseries from the early 80's do yourself a favor and hole up on some rainy Saturday and let Alec Guiness as George Smiley teach you life lessons about spying for Queen and Country. The other source for me is THE SANDBAGGERS. A wonderful ITV show that played in the UK from 1978 to 1980. Both of these are hyper-realistic... or what I imagine to be hyper-realistic... depictions of the work a day world of the counter-intelligence officer. So that is the short story to why Keith Thomson's ONCE A SPY ended up on my plate. The hook for ONCE A SPY is Alzheimer's. Drummond Clark is the leg...
