Madness in Brewster Square

Ava Maria Sophia Cecilia has been conned into her into helping her brother, Giuseppe, with one of his paranormal investigations. She really hates it when she gets dragged into his ghost-hunting gigs, especially since she probably doesn’t believe in ghosts.
But on the night they investigate the old McAllister place, the one house Ava is convinced is truly haunted, a dead body turns up in the basement.
Ava is determined to investigate the death, even when it means she cannot avoid the new detective in town, the mayor, assorted ghost-hunters, and a crazy animal rehabber. As the investigation unfolds, she starts to wonder: has everyone in Brewster Square gone mad?
