The Remains of the Dead - A Ghost Dusters Mystery

Sadie Novak’s got the kind of job that kills cocktail chatter dead: she owns Scene-2-Clean, a crime scene cleanup company. As if cleaning up after grusome murders weren't creepy enough, she can also see and talk to the ghosts of the victims.
 
When grieving relatives hire Sadie and her employee, ex-cop Zack Bowman, to clean up after the murder-suicide of Trudy and Grant Toth, Sadie figures she’s bound to meet at least one chatty ghost. But Kent, the man Sadie first encounters at the scene, is very much alive—so much so, that Sadie soon finds herself agreeing to a date with him.
 
Then a real ghost shows up—the oddly silent spirit of Trudy, who seems determined to prove her husband’s innocence, and inspires Sadie to track down the real killer. But as she scours the crime scene, Sadie quickly realizes she's in way over her head, that Kent has a strange connection to the dead couple, and that someone wants her to give up the ghost…for good.
