Breathing underwater - Marie Darrieussecq

Without telling her husband, a young woman drives off to the coast.
She takes only her young daughter, and ten thousand francs.
They spend the first night camping on the beach, and then rent an apartment in a small seaside town near the Spanish border.
She is careful to leave no clues.
But a detective is already looking for them, and he knows it will only be a matter of time before she makes a mistake . . .

'There are very few writers who may have changed my perception of the world, but Darrieussecq is one of them.' Francis Gilbert, The Times
