I've used Calahurst as a setting for my first three books and while I have recycled elements - one house in Smoke Gets in Your Eyes got a new owner in Breathless - I created another village (Port Rell) for my fourth book. And then I got very ambitious and added 'historical' legends - Civil War battles and sieges, and a notorious smuggler who turns up out of nowhere and then vanishes one day in much the same way. I had so much fun with that, I'm doing it all over again for my next two books. I have a new village, Buckley - previously mentioned in Nemesis, and a whole lot of new characters to get into trouble.
It really is the best part of being a writer.
My Pinterest board for Breathless has more photos of Lymington in the New Forest, which helped to inspire Port Rell (along with a few other places!)
My Pinterest board for Nemesis has more photos of Penrhyn Castle
