If you've already done those 5 quests Gyudan mentioned (beginning with "A Spy in Shornhelm", quest giver is Adusa-daro), try looking at the UESP Rivenspire quest list. There's also two quests that you get by killing named enemies - Nedras the Sly near the Westmark Moor Dolmen drops a journal which starts "A Lucky Break", and Klaandor Axe-Bearer near Veawend Ede drops a journal which starts "Last Words".

If its DC hero, you should also look beyond Rivenspire. You need to check all the DC zones. There are a few quests that start in the off-shoots, instead of the main paths, of the bottom of some of the solo dungeons. Found one in Alakir when helping a lower level guildie with .. sigh.. dont remember which one.. but it was a quest to give the dead guys journal to his wife.

Thanks for the tips, guys.

I've completed all of the other DC zones except Rivenspire. I will go back and look for the named NPCs to kill. I think I've done the Adusa-daro quests. I will go back through all the public dungeons again. Last time I went through there it was before they nerfed the difficulty, so I may have skipped some of the quests.

Even the delves have quests to complete in the main towns too. Normally returning goods or relaying news to loved ones or associates.

Yes, I found two quests from the named characters Enodoc suggested, one in North Point (some Argonian looking for her guar), one in an delve I had already cleared, and one in some ruins I had already cleared.

I rode around Shornhelm earlier when I was looking for quests and found a couple, so yes, it's a good idea to go back to the towns.
