Nate the Great Goes Undercover — Marjorie Weinman Sharmat

Nate the Great has his first night case! Somebody is raiding Oliver's garbage can each night, but who? The list of suspects is long -- Rosamond and Esmeralda, the girls down the street; Rosamond's cats; and all the shrews, moles, skunks, birds, and raccoons in the neighborhood. Nate courageously encounters a skunk (nose first) and a telephone pole (head on), but not until he goes under cover of the garbage-can lid does he narrow the suspects down to one.
