Talk to the archaeologist about another spellbook to start the quest. Talk to a level 2 man in Al Kharid, and ask for a spellbook. When he refuses, attack the man. Stop attacking the man halfway and talk to him again. You will receive a "Spellbook". Read the spellbook to find that it is not a spellbook, but a message telling you to attempt to light 5 yew logs in a line in Varrock. Light 5 yew logs in a line in Varrock, wait until the fires go out, and pick up the ashes left by the fire.
