I want to thank my wife, Katrina Myers, for putting up with me while I was writing this book. My whole family have been immensely supportive while I’ve been absent at weekends (thanks Mum, Dad, Oz and Ash). Notable professional mentions include Lars Malmqvist, Denis Kaminskiy and Alex Weinle at Arcus Global Ltd and the whole team at Vigilant Software, but I would like to thank all those who have helped me in my second career – you know who you are (Witchford Archers rock!). And, of course, Becky and Hazel have done a magnificent job of wrestling my awkward prose into shape.
