After her last encounter with a serial killer, Gabby St. Claire feels her life is smeared with the stain of tragedy. Between the exhaustion of trying to get her fiancé back on his feet, routine night terrors, and potential changes looming on the horizon, she needs a respite from the mire of life. 
At the encouragement of her friends, she takes on a short-term gig as a private investigator: a cold case that’s eluded investigators for ten years. The mass murder of a wealthy family seems impossible to solve but quickly gets interesting as Gabby brings more clues to light. Add to the mix a flirtatious client, travels to an exciting new city, and some quirky—albeit temporary—new sidekicks, and things get really complicated. 
With every new development, Gabby prays that what she’s calling her “mucky streak” will end and the future will become clear. But every answer she uncovers leads her closer to danger—both for her life and for her heart.
