A Dark Deed Needed?

[Hansel]

It has come to my attention that this town desires to have a Dark deed done on its behalf.  I am willing to perform a task that will greatly please Dark.  All I require is one flask of holy water, one dose of Poison of any type, and 10 Gold Pieces.  At the completion of the task, I shall clearly and loudly proclaim “This has been done for the betterment of Rowans Crossing!”
 
If this sounds like a mutually beneficial arrangement, please respond here.  I will visit the town soon to finalize the agreement.
