Who Invited the Ghost to Dinner?

Cam Shaw is hoping that her life will be ghost-free from now on. But that hope dies with the appearance of Mac "the Faker" Green, a wise-cracking ghost from Vegas who has followed her grandmother home. And during the opening night of Blithe Spirit, someone has sent Susan Ingram to her ghostly afterlife. What does her death have to do with the death of her mother-in-law fifty years ago? Who is trying to wipe out the Ingram family one person at a time? And when will that Vegas ghost stop sticking his nose into Cam's business?
