Empty Envelope (Turtleback School & Library)

E is for Envelope…Dink keeps getting envelopes in the mail addressed to”D. Duncan.” But the letters inside all start with “Dear Doris” and don’t makeany sense! Josh and Ruth Rose think someone’s playing a trick on Dink. But Dinkis sure there’s more to it than that, especially after Doris herself shows upand demands her letters!
