The sleepless night of an old man in his vast library, an unfathomable place, not simply in its size but because it is the extension of a human being, the one who created it. A library haunted by ghosts. The old man doesn’t see them. Are there ghosts around us that we can’t see? Can ghosts see us? Can ghosts see each other? The books in a library cohabit on the same shelves but do the characters in the books know each other? A book always makes one think of another, read or to be read. Books and their characters haunt our minds. The reader is a medium, possessed, he makes the link between books, their characters, the thoughts of their authors and his own.
