Senior snoop, Agnes Barton, has taken up residence in a Winnebago at a campground in East Tawas, Michigan. It’s not the ideal place for a woman of seventy-two to live, but she’s making do. She had planned to start a detective agency with partner in crime, Eleanor Mason, but a snag with the license has them free wheeling it, not that it matters because they are the ones folks call when dead bodies turn up.
A frantic phone call has Agnes and Eleanor racing to the scene of yet another crime scene. Herman Butler has fallen to his death from a third story window, and the widow, Betty Lou, is beside herself with either grief or competing for the Oscars, and it’s up to Agnes and Eleanor to unravel the mystery, which gets more interesting when a ghost is listed as a possible suspect.
This time around, Agnes and Sheriff Peterson can agree, the widow is nuts, but wait, a few days later the ghost ship, Erie Board of Trades, was spotted off the shores of Lake Huron. Ghost hunters, G.A.S.P., hightail it into town, and East Tawas is overrun with ghost sightings.
Agnes and Eleanor must sort fact from fantasy before another body is found or a curse is realized.
