Read the excerpt from Act 2 of The Monsters Are Due on Maple Street.

68. MED. CLOSE SHOT – CHARLIE 68.

On the front porch as a rock thrown from the group smashes a window alongside of him, the broken glass flying past him. A couple of pieces cutting him. He stands there perspiring, rumpled, blood running down from a cut on the cheek. His wife breaks away from the group to throw herself into his arms. He buries his face against her. We can see the crowd converging on the porch now.

VOICES

It must have been him.
He's the one.
We got to get Charlie.

Another rock lands on the porch. Now Charlie pushes his wife behind him, facing the group.
