The Mystery at the Rodeo Ranch

The second story in the Stables Mystery Series. Three eleven-year-olds-a girl from Hawaii, a boy who is Black, and a girl who is Caucasian-have their own detective agency to solve cases. Their case this time is who is doing stuff on Rodeo Ranch-like letting the bull out. Is there really a Calico Ghost? When they find that out, really bad stuff starts happening. Are they in over their heads-or will they be able to solve this case, too?
