'I wonder if it hurts them to shed their skins,' she said. She didn't feel afraid standing in the darkness, imagining snakes, even with the smell of death in the air. Bea and Dan, recently married, rent out their tiny flat to escape London for a few precious months. Driving through France they visit Bea's dropout brother Alex at the hotel he runs in Burgundy. Disturbingly, they find him all alone and the ramshackle hotel deserted, apart from the nest of snakes in the attic. When Alex and Bea's parents make a surprise visit, Dan can't understand why Bea is so appalled, or why she's never wanted him to know them; Liv and Griff Adamson are charming, and rich. They are the richest people he has ever met. Maybe Bea's ashamed of him, or maybe she regrets the secrets she's been keeping. Tragedy strikes suddenly, brutally, and in its aftermath the family is stripped back to its rotten core, and even Bea with all her strength and goodness can't escape.
