Don't Go Near Mrs. Tallie (Hardcover, Turtleback School & Library ed.)

Someone is out to get Mrs. Tallie!

Rosie Saunders was just trying to help when she talked her best friend Kayo in to finding a home for Mrs. Tallie's cat, Muffin. It should have been an open-and-shut case for the Care Club ("We Care About Animals"). But then a creepy caller warns them to stay away from the sweet little old lady. Why? Mrs. Tallie is sick and seems to be getting sicker each day. But when they find the poisonous plant near the gardener's shed, Rosie knows someone is trying to kill Mrs. Tallie. There's no time to lose if they're to save their friend. Now it's a race to catch the killer-- before he catches them!
