Stevie D

Stevie D, a.k.a. Steven Douglas, is professional assassin. He appears in Changes.

Description
Stevie D is a blocky professional assassin who killed Torelli a few years prior. Harry had heard of him before.

In the Series
In Changes, Stevie D shows up at Saint Mary of the Angels, where Harry Dresden, his back broken, has gone seeking shelter from the Eebs who can't enter the santuary. Stevie D shoots Waldo Butters twice to get him out of the way, then aims at Harry's head. Harry utilizes his new ability access ice in a spell—"Arctis!"—that freezes the gun. Stevie drops it. Father Forthill tackles the assassin, who kicks him in the nose. Butters zaps Stevie with the naked wires of the defib unit. After Stevie comes to, Harry questions him. After Harry threatens to inform Marcone on him, he reveals that a woman matching Susan Rodriguez's description hired him to kill Harry. As agreed, Harry releases Stevie D.

Harry deduces that it was the Eebs, not Susan, who hired Stevie D to kill him inside Saint Mary's. Esmeralda Batiste can make Stevie believe she was Susan with her eyes. And it's exactly her style.

Character
He seems to genuinely care whether Waldo Butters survived being shot by him. He asks how the little guy is and he's relieved to learn that Butters was wearing a Kevlar vest. He says he wouldn't want to do time for killing the wrong guy. Everything he heard about Harry, told him that he couldn't play around and needed Butters out of his line-of-sight.
