Justice for Hire: A Private Investigator Mystery Series

A young girl who has been missing for eight months suddenly reappears and commits a heinous murder. She claims not to know why she did it, or where she has been for the last few months. The girl's desperate parents hire private investigators Jake and Annie Lincoln to find the truth behind their daughter's disappearance, and why she would return and kill a stranger in cold blood.
An ex-con, who had seemingly turned his life around, becomes the next victim when a young boy shoots him, then casually holds the gun to his own head and pulls the trigger. An aspiring city councilor is executed in the same manner. None of the murderers seem to be aware of their actions.
