Pierre Bayard is the founder of "interventionist criticism", he is opposed to neutral and uncommitted criticism of literary works. In the course of his essays, he has, among other things, chased down unpunished literary criminals (due to the negligence of their creators), provided tips and tricks for talking about books and places that have not been read or seen, or reflected on the resistance/collaboration dilemma.
Bayard's most popular book, How to Talk about Books You Haven't Read [fr] (Minuit, 2007), is a bestseller in France in which he engages in a study of the different ways of not reading a book, and recommends solutions to be able to talk about it anyway. Assuming that some readers have a terrifying understanding of reading, he tries to make them feel free from guilt for not having read canonical literature. The essential thing in culture being to have an overview, he claims the possibility of having a perforated and incomplete culture. Pierre Bayard has renewed this system in Comment parler des lieux où l'on n'a pas été, a work in the second degree again, in which he reviews the authors who have spoken of places they have not visited.
In 2019 returned to an other book by Agatha Christie, And Then There Were None and questioned the solution delivered to the outcome of her novel. His entire book is therefore the counter-investigation that must restore the truth: we find in fact the procedure he already used earlier: attempts to rectify certain fictional police investigations that he considers unlikely. And he proposes to come back to a new literary misunderstanding and shed light on a mystery that no one has solved, not even Agatha Christie. The novelty this time being that he lets the real murderer of the And Then There Were None speak for himself to lead us to the only acceptable solution.
His book on Hamlet argues that Claudius did not kill Hamlet's father. In these essays on Agatha Christie, Shakespeare and Conan Doyle, he engages in real literary counter-investigations, studying the motivations of the characters, highlighting the inconsistencies of the intrigues and humorously showing that fictional characters escape their creators.
Moreover, humour is a fundamental element of his writing. In How to Talk about Books You Haven't Read, the narrator teaches the way not to read, which is a joke because he himself is a great reader. For Pierre Bayard, humour has an analytical function. It allows you to mark a gap between yourself and yourself, and therefore to distance yourself from what you read.
