"The Empty Envelope" A to Z Mysteries children's book by Ron Roy 

"Dink keeps getting letters addressed to 'D. Duncan.' But when he opens them, they all start "Dear Doris' and don't make any sense! Josh and Ruth Rose think someone's playing a trick on Dink. But Dink is sure there's more to it than that -- especially after Doris Duncan shows up and demands her letters.!"
