Detailed Walkthrough
Tienius Delitian
Speak with Tienius Delitian in the Royal Palace Throne Room again and agree to help him investigate a possible plot against King Helseth. You are to search the Llethan Manor in Godsreach for any possible documents that might provide evidence of such a conspiracy. Tienius warns that the widow of the dead king, Ravani Llethan, lives there and has a good number of guards, and he suggests you go there under the cover of offering your condolences to her.

Llethan Manor
The Llethan Manor is in the northwest corner of the Godsreach District in Mournhold. Ravani is on the ground floor if you wish to speak with her, though no one will bother you anyways. Although there are large safe areas where no one will witness your search, the document needed for this quest is a handwritten letter lying on the desk in the same room as Ravani. Use chameleon/sneak or whatever you need to get away with taking the letter. If you are caught stealing, she and the other people in the building will attack.

Return to Tienius
Return the handwritten letter to Tienius and he will offer you the opportunity to kill three people involved in the plot to kill the King: Forven Berano, Hloggar the Bloody, and Bedal Alen. He gives you writs for all three and gives you some vague suggestions on where to start.

Forven Berano
Tienius suggests to look for him around the Temple area. Indeed, Forven is wandering the grounds at the north end of the Temple. If you confront him with the "Evidence of Conspiracy," you have the option of killing him or letting him escape.

Hloggar the Bloody
Tienius suggests looking for this Nord in the sewers. Speak to a High Ordinator and they'll tell you to look for him in the West Sewers. Head to the northwest corner of Godsreach and go down the trapdoor into the Residential Sewers. From there, follow the tunnels east and south a short way until you find the ladder leading to the West Sewers. Head up the ladder and turn west, following the cave tunnel as it twists and heads back to the south. You will find Hloggar just as the caves emerge into sewer tunnels.

Bedal Alen
Unfortunately, Tienius has no idea where Bedal might be. Talk to a High Ordinator, however, and you might be told that he is a bookworm, so check at a bookseller. Check out the bookshop in the Great Bazaar and you'll find Bedal upstairs. Again, confront him with "Evidence of Conspiracy" and either kill him or let him escape.

Return to Tienius
Once the three are dealt with, return to Tienius to receive a maximum reward of 3,000 gold, minus 1,000 for each target you let go.

Notes
If you are a member of House Hlaalu, be sure that nobody witnesses you killing any of the conspirators. All three targets are members of House Hlaalu and if anybody sees you kill them, you will be expelled.
You can kill all three targets before the quest starts and Tienius will not object.
TR08_Hlaalu_Ravani 1 and 5 cannot actually be obtained. There is no journal entry for those unlike the other three. You can still offer your condolences and swear to avenge their death but won't get a journal entry for it.
