Gertrude in South Dakota

"There's no such thing as ghosts! Right?" Gertrude thinks she's got a knack for proving that ghosts don't exist, but this time she's taking on a celebrity phantom: Seth Bullock. She and Calvin pack the cats into the camper and head to Deadwood, where she will attempt to prove herself right once again. But shortly after she gets there, a movie star drops dead, and she finds herself with two cases to solve. Maybe the two cases are even connected? The mysterious green feathers she keeps finding everywhere seem to suggest that they might be. Is she getting a little sleuthing help from the great beyond?
