The UESP has a couple solutions:"Although most of the NPCs needed for the quest to initiate are marked as essential, another quest, namely the Dark Brotherhood quest Mourning Never Comes, will encourage you to kill Nilsine Shatter-Shield. Even though she is not related to this quest, her mother, Tova Shatter-Shield, will commit suicide if Nilsine is killed, and will therefore render this quest impossible to initiate."And "Arivanya, the [Windhelm] stable hand, is also needed for this quest to trigger, but is not marked as essential."
