Elliot Cross is the Butterfly Killer. He targets anyone with dreams and aspirations. In this short story we are introduced to his cunning ways. He stops at nothing to gain his victim's confidence. If you have a dream, he's ready to make sure you don't live to achieve it. It doesn't matter how simple or elaborate. As you see in this short story The Driving Lesson, the dream can be as simple as a teen boy anticipating passing his driver's test.

Excerpt

Timmy thought it was odd that Carrie’s Father didn’t want anyone to know about the Sunday driving lesson. He churned it over and over in his head, Mister. Cross’s reasoning for the secrecy. 
“Your friends will be as mad as wet hens if they fail to pass and they find out you passed because you had an extra lesson. I can just hear my Carrie, ‘But Dad, you gave Timmy private lessons, but not your own Daughter?’ Whoo! That gal can be jealous. But you know her. You and her are tight like a drum aren’t you?”
That explanation sounded reasonable to Timmy. Kids at South High tended to act like crabs in a barrel. If half of Mister Smith’s Trig Class was failing, they all had to fail. Shining stars weren’t tolerated. And Mister Cross was right about his daughter Carrie. Most kids shied away from Carrie, partly because of him and his crazy love for chasing butterflies all over the neighborhood. But she also had a jealous streak that was about as green as her hair. Girls didn’t stay friends with her very long. Even other lesbian girls fell victim to her rants and arm twisting because she had caught them talking to boys or other girls. But Mr. Cross had put his hand on his shoulder in a most fatherly way. Or was that creepy, Timmy wondered? The hand lingered a moment longer than it should and squeezed harder than it should have--an unwelcomed massage.
