[font=arial][SIZE=2]In the library you need to locate the 4 books mentioned in Richard Morton's will and push them into place in a certain order which is... Light/Dark/Dark/Light. The two Light books are on the top floor - one at the very end of the walkway and the other further back behind a pillar. The other Dark books are on the bottom floor, one at the bottom of the steps and one behind the ancient statue. Once the last book is in place the final portrait opens.
Remember the order... Light book first, then the two Dark books and finally the other Light book.[/font][/SIZE]
