Second Thoughts () is a novel by Michel Butor first published in French in 1957. It is the author's most famous work. It was translated into English by Jean Stewart, with the title Second Thoughts (Faber and Faber, 1958) as well as under the titles A Change of Heart (Simon & Schuster, 1959) and Changing Track (Calder, 2017; revised translation). Plot summary The plot is quite straightforward: a middle-aged man takes the train from Paris to Rome to visit his lover, Cécile, whom he has not informed of his arrival. They have met in secret once a month for the past two years: each time that his business trips have taken him to the Italian capital. He now intends to tell her that he has finally decided to leave his wife, found a job for her (Cécile) in Paris and is ready to take her back there and live with her. The novel describes his gradual change of mind. His initial enthusiasm and hopes of a rejuvenating new start slowly give way to doubt, fear and cowardice. He eventually decides to spend the week-end in Rome alone, go back to Paris the following Monday without saying anything to Cécile and leave the situation as it was until their relationship eventually ends. He will write about this failure in a book which happens to be "La Modification" itself.

La Modification contains both realistic and fantastic elements. On the one hand, the various landscapes, the passengers, the interior of the carriage are described down to the last detail. On the other, there are many eerie episodes. For instance, as the train passes the Fontainebleau Forest, the main character sees the "Grand Veneur", a ghost rider that is rumoured to haunt it and ask questions to the persons he comes across. It reappears several times in the book (thus becoming a leitmotiv). Its questions always echo the state of mind of the main character: "Can you hear me?", "Can
