Andrews, Donna. Meg Langslow mysteries.

Meg Langlsow volunteers to help her parents when the Caerphilly Garden Club sponsors its first annual rose show. But after a few hours of dealing with her parents' competitors, Meg is worried--someone is attempting to kill the wealthy woman on whose estate the competition is being held. Could it be one of the eccentric rose growers after the coveted Black Swan trophy? Or one of the animal welfare activists--which includes Meg's zoologist grandfather--resorting to murder against the intended victim's treatment of farm animals?
