I have always been rather fuzzy concerning the real-world chronology of the story, writing with a vague awareness of the late nineteen-twenties for the background (Jules' car is a 1928 Mercedes SSK, Lord Lawrence served at Ladysmith "almost thirty years ago", the Breguet 280T came into service in 1929 etc.), but I have never really wanted to tie it down exactly, hoping I could get away with a somewhat fictionalised 1920s.
Whether JoaquÌn has caught me out or not, I greatly enjoyed his accurate research, and think Rainbow Orchid isn't breaking too many of the laws of time just yet. So here's his analysis, and after you've read it, go and check out his exciting-looking 'Creation: The Making of Kong' project - where you'll find our timelines may well intertwine somewhat.
While drawing over the weekend I listened to an advance copy and it is really excellent, very entertaining. You can listen to a trailer from the website. If you like Rainbow Orchid, I'm sure you'll like The Scarifyers.
