Best-selling author Leila Slimani and Fanny Herrero, the acclaimed writer of the French TV series Call My Agent, revealed in an interview on Tuesday that they have been collaborating on the opening ceremony of the Paris Olympics.
Slimani, the Franco-Moroccan author of Lullaby, a book about a killer nanny, called it a "huge honour" to be asked to take part having arrived in France as an 18-year-old.
