The Raid

Walkthrough
After Helping Hand convince Wujeeta to reveal from whom she got her skooma. Persuasion, or Intimidation should do the job.

Identify Riften's skooma dealer
She will drop the name Sarthis Idren and that he has a base in the Riften Warehouse.

Report Sarthis Idren to the Jarl of Riften
Relay the information to the Jarl of Riften. The Jarl will know of Sarthis, but so far the dealer has evaded any attempt to nail him down, due to a good working network of informants as it seems. An outsider, like the Dragonborn could have more luck. If agreed the Dragonborn receives the Riften Warehouse Key.

Enter Riften Warehouse
Enter the Riften Warehouse down at the docks and use the key to unlock the door.

Eliminate Sarthis Idren
Orini Dral, Sarthis' muscle will immediately attack, take him out and also Sarthis Idren himself. Get Sarthis's Key from the latter's body.

Recover skooma source information
Then search the cellar for Sarthis's Satchel and retrieve the note Shipment's Ready and read it. It details Sarthis's sources.

Report skooma source to Jarl Liela
The Jarl will be thrilled about the success so far, but there is more work to be done in Supply and Demand.
