Gertrude is famous for proving ghosts don't exist, but this time she's taking on a celebrity phantom: Seth Bullock. When a movie star dies at the famous Deadwood hotel, she finds herself with two cases to solve. Are her two cases connected? The mysterious green feathers she keeps finding everywhere seem to suggest so. (This standalone story is Book 2 of the Gertrude in South Dakota Mystery Series, which is a continuation of the Gertrude, Gumshoe Cozy Mystery Series.)
