The Case of the Graveyard Ghost: Doyle and Fossey

Drake Doyle and Nell Fossey are not only close friends, they are also first-rate science detectives-the best in the fifth grade. In four perplexing cases, the team encounters a noisy cupboard, white roses that have turned a revolting color, a ghost who demands money, and endangered parrots for sale at a local pet store. Each story explains a different science concept. Includes activities and experiments. Black-and-white illustrations.
