Read the excerpt from "Object Lesson, Part 2." "But this morning's little job," Ellery turned suddenly to the red-haired boy, "you pulled by yourself, Joey." The thin boy quivered. "Who, me?" "Yes, Joey, you." "You got rocks in your skull," Joey whispered. "Not me!" "I'll prove it, Joey. Hand me the dollar bill I found in your jeans when I searched you." Why do these words create tension? They create an uncomfortable situation for Joey. The sudden movement surprises the reader. They make the reader wonder what happened before. They speed up the pacing of events.
