Gertrude, Gumshoe: Gunslinger City - Gertrude, Gumshoe Cozy Mystery Series, #5

Gertrude's never been so busy. There's been a murder at a Wild West theme park, and Gertrude is on the scene. But she can't stay long, because there's been another murder in Mattawooptock. To complicate matters, Deputy Hale has lost his patience with her eccentric sleuthing. Can she avoid his handcuffs long enough to solve a murder? Or two? (This is Book 5 of the Gertrude, Gumshoe Cozy Mystery Series.)
