The Dresden Files: Portland
Mercenary Alpha Wolf
Darla was hired by the new Red Court Margrave in Seattle, Diego Aguirre de Calderon, to cause trouble for Shawn Loomis by murdering the citizens of the Snoqualmie reservation. This was a ruse to draw Loomis from Seattle in order to set up his “Special Crimes” unit with the Seattle P.D.
She was caught out by Loomis and Brianna and later let go after swearing on her power to never set foot on the Snoqualmie reservation again.
