Unable to progress with Main Scenario Quests

My last completed Main scenario quest is "Power of Deduction" according to scources online the next quest in line is "Secret of the white lily" which should be available from the quest giver "Aethelmaer" but the NPC has no quest for me so i'm unable to progress :confused:. Not sure if i'm missing something or this is a bug.

EDIT: Issue solved sorry for some reason the quest backlog hadn't updated and i was further into the quest line than I thought, not sure how to remove this thread if someone could delete for me.
