One morning, the famous writer, Goncourt Prize winner Pierre-Marie Sotto finds a thick package in his mailbox. Another manuscript from an unknown graphomaniac? Pierre-Marie never reads other people's manuscripts! He is about to send the package to the sender, but there is no return address, only the email of a certain Adeline Parmelan. To find out the postal address, Pierre-Marie writes a letter to Adeline, receives a slightly strange answer, writes a new one, receives another answer and... gradually gets drawn into the correspondence, which soon ceases to be formal and captures both participants. The mysterious package lies unopened on the shelf of the bookcase, as if waiting for the writer, who is experiencing a severe personal and creative crisis after the mysterious disappearance of his wife, to wake up from melancholy and again believe that life is beautiful. “And I also dance” - written “at four hands" is a touching and witty novel about lost and regained love, about two lonely hearts who suddenly turn from extras into the main characters of a gripping drama.
