Killer Ghost: A Christie's Flower Shoppe Mystery (Christie's Flower Shoppe Cozy Mysteries Book 4) by PJ Peterson

Christie didn’t believe in ghosts. Until she met one. Decorating for elegant weddings and receptions was Christie’s passion. She felt squeamish, however, when the bride-to-be announced that the venue was a haunted mansion, at least according to the locals. When she and her friend Anita went upstairs to look for the cause of noise they had heard from the ballroom, they discovered an orange tabby cat sitting next to an overturned chair on the floor. Ghosts indeed! But after a young lady falls to her death from the padlocked widow’s walk, Christie begins to wonder if there might be some truth to the rumors. Or is someone trying to sabotage her business?
