Trick Or Treat Or Murder by Janet McNulty

While working at the Candle Shoppe, a man rushes in demanding to speak to Mel. He tells her that someone is trying to kill him and then drops dead. Though the coroner informs her it was a heart attack, Mel cannot get the man’s words out of her head.

Soon she is drawn to an abandoned inn that dates back to 1688 and the legend of Smiley’s Ghost. With the help of her friends, Mel explores the abandoned inn and soon finds herself being harassed by a black rider on a horse. Knowing that all is not as it seems, Mel must discover the secret of Smiley’s Ghost and the inn before she becomes the killer’s next target.
