I've been planning a mod that allows a 'good' character to go through the Dark Brotherhood as a 'double agent' reaping similar rewards (only good versions of them) and using similar quests, however I need a few ideas.

Does anyone have any ideas as to how the following quests could be completed in a good-ish fashion (I've got ideas for the rest that I'll be putting out soon.)

- A Knife in the Dark (I've got some ideas but others are welcome) - http://www.uesp.net/...ife_in_the_Dark
- Accidents Happen - http://www.uesp.net/...ccidents_Happen
- The Lonely Wanderer (again, I've got some ideas) - http://www.uesp.net/...Lonely_Wanderer
- Whodunnit (no idea how I'll pull this one off) - http://www.uesp.net/...ivion:Whodunit?
- Next of Kin (some ideas already) - http://www.uesp.net/...ion:Next_of_Kin

The group that the player is working with is NOT allied with the brotherhood's traitor
Any help would be much appreciated.
