Storyline Quest missing

I finished the quest "Power of Deduction" and turned it in. After turning it in I didn't see any new quest givers nearby so I looked online and saw that the next quest in the line is "Secret of the White Lily" and the quest giver is Aethelmaer. So I go find Aethelmaer but he doesn't have any quests to offer. Online it says the only requirements for the quest are being the right level (at least level 28) and having done "Power of Deduction". I've traveled around for close to 8 hours looking for a storyline quest still haven't seen any. Please help!

PS: I've added screenshots incase that might help...http://imgur.com/a/twLZb

I suggest that your read your CS because it clearly said to go back to Waking Sands

Also read your own SS because you finished Secret of the White Lilys

sheesh people these days
