The Butler Didn't Do It — Claire Robyns

Once again Maddox Storm finds herself at the center of a murder, and not the one she artfully arranged.

Desperate to turn Hollow House's newfound dark fame into a money-making machine, Maddox hosts her first murder mystery weekend. But what starts out as a surprising success is bludgeoned by the all too real death of one of her guests. And worse, now they're refusing to leave. They came to solve a murder mystery and by gosh, that's exactly what they intend to do.
Events quickly spiral out of control and before Maddox can say whodunit, she's sharing a house with her soon-to-be-ex husband, the smoky-eyed Detective Nathanial Bishop, a litter of Sherlock Holmes wannabes and a cold-blooded killer.
There's only one thing to do, really. Roll her sleeves up and solve the murder before the lot of them drive her off the deep end.
