Nicola here. Since the time I first picked up a book I’ve been fascinated by islands, both in real life and as the setting for stories. Whether it's Five on a Treasure Island or The Island of Adventure by Enid Blyton, or Robinson Crusoe or Lord of the Flies (well not so much that one, perhaps) there is something magical about an island.
Islands offer the idea of escape and retreat and also the opportunity to start afresh. They are places set apart where you can take time and space to think. They appear solitary and pure in some ways, an earthly paradise. But they can also be too isolated, even savage, which is perhaps they make such great settings for crime novels. An island, if you can’t get off it easily, is the perfect “locked room” mystery as Agatha Christie proved and countless other crime and thriller authors have used the setting.
