The Great Scarecrow Invasion

After their latest assignment is debunked before they can even get started, Irene Waters and Troy Stenson take the opportunity to help out an old friend.
Bob Cullens has been sidetracked from his retirement to design an elaborate corn maze for the Franklin family. But now he has trouble. Scarecrow trouble.
So what could be the trouble with scarecrows in a cornfield? Well, they’re getting up, walking around and making a general nuisance of themselves. Then there's that whole curse thing that this could have dire consequences for the Franklin Clan.
But Bob's not worried.
Because he knows that for Irene and Troy, this is just another day at the office.
