You killed the quest giver Wulf Wild-Blood or his brother Torkild? If you killed the quest giver you couldn't accept the quest. If you had killed his brother before accepting his quest, but the corpse has disappeared, I don't know whether the game would spawn a new Torkild but you can try. There's no quest marker in this quest. You have to travel from place to place in Sosltheim to look for Torkild.
