It's a tough 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 racoons in the neighborhood. Nate courageousely 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.
