Absolutely my favourite narrative environment designer, Crystal is someone I’ve known since she’d crawl barefoot under my dining room table in a gorgeous jewel of a dress handsewn by her mum, but to my parents’ everlasting horror, sans knickers. Look what’s she’s grown up to be – and do! And yes, she does match the Portuguese tiles. (I have told you before, haven’t I, that every one of my books has an important character with tattoos?)

Go on, explore her website, you’ll love it.
