Stirring in the bushes, hid Tom Riddle. Here he was, at the house of Harry's grandparents. To fulfil the prophecy made before the boy's birth. Harry put a key in the lock, and stumbled in. He would be weak with emotion when Voldemort struck. He would die. Voldemort would be at large again.
A dream come true, but also a nightmare.
Tom stood up, and silently slipped through the door, which Harry had left open. Like a snake, Tom edged into the hallway. Next to the door, where Harry was reading Lily's diary. Or part of it, anyway.
Harry was lying on the sofa. It was now or never.
Raising the wand almost identical to Harry's he began to mutter the killing curse.
"Avada Ke-"
He was cut off, by another killing curse, right at his back.
"AVADA KEDAVRA"
It was Dumbledore. But Voldemort wasn't an ordinary wizard. The spite and hatred for Harry kept him alive long enough to finish the curse. The whole room turned green, and was then, nothing.
But the bodies of the two most loved wizards, and the one most hated.
