Rebecca Latté is a famous actress in her fifties, perhaps past the peak of her career. Oscar Jayack is a middle-aged, moderately successful author who, in the wake of the `MeToo movement, has been accused of sexual harassment by his former publicist-turned-feminist blogger Zoë Katana. When Oscar insults Rebecca's appearance on Instagram, she sends a scorching reply and the pair fall into a spiral of mutual antipathy. In back-and-forth emails, they vie for the last word, finding common ground in their experiences of addiction, assessing the changing world around them as COVID locks down Paris, and reluctantly beginning to lean on one another. A novel of rage, irreverence and vulnerability, exploring ageing, gender, privilege, addiction and consent, 'Dear Dickhead' is an excoriating encapsulation of our times and of the broken human beings trying to make sense of it.
