"While pedaling his bike frantically through the streets of Lille, striving to deliver as many hot meals as possible, our hero is involved in a traffic accident. He emerges relatively unharmed, but finds his account "disabled" by the algorithms of the app he was working for. As a result, he is left without income or a source of livelihood. In the midst of this difficult situation, he hears about a strange profession: "secret agents," people assigned by companies to pretend to be ordinary customers in order to evaluate employees' performance without their knowledge. Thus, he joins the ranks of these secret agents, who work in the service of the modern management system, and ends up becoming a direct and indirect suspect in more than one murder and suicide! The novel "The Secret Agent" offers a vibrant and tense portrayal of the world in the age of the digital economy, which seeks to maximize the use of available resources, where algorithms control everything, and human relationships are erased in favor of absolute efficiency. It is a novel that reveals the details of this secret system and the impact of the economy and capitalism on all of our lives."
