Killing at the Carnival

Cassie Pengear thought a visit to the carnival would be fun: see some shows, eat some sweets, help her landlady’s nephew decide if the cowboy was real or an actor. But then the cowboy shot the volunteer, and he didn’t get up. Now Cassie has a ten-year-old boy insisting the cowboy isn’t a killer and a landlady insisting she help solve the killing at the carnival.
