Loose Screw - Nailed It Home Reno Mysteries, #2

All Rowena Summerfield wants to do is finish her latest home renovation with her daughter, Valerie. And it seems like all building inspector Mortimer Fonseca wants to do is get in her way. His refusal to help Ro's Nailed It company meet his impossible expectations has her fuming, and she's not the only one - as she learns when Fonseca turns up dead, run over in a parking lot in the middle of the night. His colleagues say he was a loose screw, even if he was wound too tight.
But Ro and her former colleague on the police force, Detective Hercules Morgan, soon discover he was a lot more than that. And a lot of people might have wanted to wrench the life out of him, from disgruntled builders to his sneaky co-workers to a relative who stands to inherit everything. The more Ro, Val and Herc interview suspects and other persons of interest, the less they are able to hammer down a motive.
But as the case takes an unexpected turn and becomes doubly complex, can a voice from beyond the grave be just what they need to nail down the guilty party?
