The Remains Of The Dead

Description for THE REMAINS OF THE DEAD by Wendy Roberts:

Sadie Novak has got the kind of job that kills cocktail chatter dead: She owns Scene-2-Clean, a crime scene cleanup company. And if wiping up after murders weren't spooky enough, she can also see and talk to the ghosts of the victims.

When a grieving relative hires 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 encounter at least one chatty ghost. But instead she finds herself talking to Kent, a man she meets at the scene who is very much alive--so much so that Sadie agrees to go on a date with him.

When a ghost does appear--the oddly silent Trudy--the spirit seems determined to prove her husband's innocence, and inspires Sadie to track down the real killer. But as Sadie scours the crime scene, she quickly realizes that 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.

This is #1 in A Ghost Dusters Mystery.
