“Avada Kedavra!” A jet of green light shot from the end of
Snape’s wand and hit Dumbledore squarely in the chest. Harry’s scream
of horror never left him; silent and unmoving, he was forced to watch as
Dumbledore was blasted into the air. For a split second, he seemed to
hang suspended beneath the shining skull, and then he fell slowly
backward, like a great rag doll, over the battlements and out of sight.
