Voldemort stood up. Harry could see him now, see the red eyes, the flattened, serpentine face, the pallor of him gleaming slightly in the semidarkness.
He took out his wand and gave a great sweeping wave with it; at once, all the candles except those inside the carved pumpkins were extinguished, plunging them into a state of semidarkness.
It was a relief when six o-clock arrived and they could slip out of their sleeping bags, dress in the semidarkness, then creep out into the garden, where they were to meet Hermione and Griphook.
