Not two, a couple: this is the critical relationship between the books. They cannot exist separately. Where Ii - The string and the pearls ends, The Goldsmith builds its central point, water being the connection element and the way to other unexpected transformations. In its turn The Goldsmith just in the words The End and in the two previous lines gives the mirror image of a couplet of Ii - The string and the pearls. Here the protagonist will not fulfil his wish, but another character, or may be the same, will make it real in the last page of The Goldsmith.
