Showing No Justice by Darcia Helle

For Michael Sykora, killing started as blind rage. Then it became something he's good at. To most of those who know him, Michael is a software designer, a smart but average guy with a workaholic nature. To a chosen few, Michael is a part-time hit man whose specialty is eliminating hard-core criminals.

Michael has managed to keep his two personas separate. Until now. When Nicki, a close friend, gets into trouble, Michael steps in to help. Having lost his fiance to a brutal crime, Michael will do whatever necessary to keep from losing another woman in his life.
