The Elder Scrolls V: Skyrim/Innocence Lost

This quest is learned through rumors from innkeepers, from the Honorhall Orphanage, or from various conversations (such as one just outside the Aretino residence.)

To begin, you need to pick the lock to the Aretino Residence within Windhelm. Enter, and speak with Aventus, who will offer the contract to kill Grelod the Kind. She is found in Riften, to the right of the keep.

Grelod may be safley killed in plain sight without incurring bounty. When she is killed, you may return to Aventus to collect the reward, a family heirloom worth 100 septums.

After you complete the quest, you will receive a message by courier. Once you get the letter and read it, you may start ../With Friends Like These.../ by sleeping in any bed.
