Unhinged (The Home Repair is Homicide Mysteries‪)‬

It began with the mysterious disappearance of Harriet Hollingsworth—Eastport, Maine's snoopiest resident. Everyone is convinced the old busybody bolted out of town to escape her creditor—everyone except Jake and her best friend, Ellie, who suspect otherwise. But they'll need to come up with proof more sinister than a pair of abandoned binoculars. Just as Jake starts poking around for clues, things take a troubling turn for the worse. A suspicious accident nearly kills her teenage son, Sam, and her husband, Wade, just misses getting his head blown off. Jake is prepared to attribute these incidents to a spate of bad luck—until another accident leaves a visitor to Eastport unmistakably dead.
