On the northern side of Hierarch Square you’ll find a bookshop called Books and Scrolls. When you enter the owner, Marcus Hodgson, will recognize you and tell you someone left a book for you years ago. He can’t remember where he placed it but says it has a red cover.
Use your Witcher senses to examine the bookshelves and pick up the one on the second floor just before the stairs going up to the third floor. It’s titled “My Manifesto – The Life of Jacques de Aldersberg“. This confirms that Alvin from The Witcher is in fact the main antagonist, Jacques de Aldersberg.
