A to Z Mysteries A: The Absent Author

A is for author.... Dink writes to his favorite author, mystery writer
Wallis Wallace, and invites him to visit Green Lawn. To Dink's amazement,
Wallace says he'll come! But when the big day arrives, Wallace is nowhere to be
found. The police think he just missed his plane, but Dink suspects foul play.
It's up to Dink and his two best friends, Josh and Ruth Rose, to find the
famous writer--before it's too late!
