It’s December in the neighboring cities of Tawas City and East Tawas, and they have one thing in common—Christmas is drawing nearer. The only problem is that homes are being broken into in alarming numbers, with guns stolen. Even local militia members Curt and Curtis Hill are victims. That is, until Agnes Barton and Eleanor Mason are on the case, launching an investigation even after the ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) comes to town, taking an interest in the recent thefts. Agnes’s own son, Stuart, who works for the FBI, tells her to back off, but Agnes isn’t about to stand down. It’s not something she does, even after a threat of arrest.

Life for Agnes and Eleanor is good, they’re planning their weddings to their respective fiancés, Andrew and Mr. Wilson, who still refuses to tell anyone his first name. With their hearts set on having their wedding at the lighthouse at the point, Agnes yet again is up to her elbows with ghost sightings, but that’s something that she’s grown accustomed to since her paranormal gift appeared.

As Agnes tries to figure out who the female ghost at the lighthouse is, she finally acquaints herself with the ghosts that live in the attic of the Butler Mansion. The deeper she gets, the more she learns about not only who they are, but the dark history of the Tawas area.

It gets down to the wire. Will Agnes be able to figure out who is stealing guns in the area, stop the ghosts from causing havoc at the mansion, and actually make their wedding plans before they land in jail or worse?
