He was sleeping relatively peacefully, lying spread-eagled on the dining room floor of the empty mansion. He jerked awake, sitting bolt upright; he glanced around to get his bearing. Tom Riddle staggered to his feet, tripping in his haste over the long gray robe he wore. He rubbed his tired red, snakelike eyes and walked over to his desk, turning over random papers on his desk.
Yes, there it was! A small pink sheet of paper labeled 'Ministry Infiltrating Hours'
10:00-10:03am and 8:15-8:19pm, perfect, it was 8:14 now.
He dissapparated, reappearing in the Ministry's front lobby though he wasn't entirely sure that was possible. Ignoring that thought he set off for the Department of Mysteries, more specifically the hall that contained the remaining Time-Turners.
A few minutes later found the Dark Lord examining each Time-Turner, deciding which to use being more difficult than he'd originally planned. He selected a medium-sized copper hourglass off the shelf and turned it a few dozen times.
He reappeared on a little street at night time and walked quickly up a narrow lane to a small white house invisible to muggles. He opened the unlocked door and strode in; silently blasting James Potter out of the way before he'd even rounded the corner. He continued up the stairs and cornered Lily in the baby's bedroom. He repeated everything he'd said last time and again she refused, willing to die to save the brat. Sighing Voldemort cast Flipendo at her and she sailed back into the wall and was knocked out cold.
"Didn't die for the boy this time!" he announced triumphantly to the air.
He walked over to the crib and peered inside, staring at the little boy drooling and looking at him.
"Avada Kadavra?" he whispered.
There was a green glow and the boy fell over only to get back up gurgling weakly a few seconds later. Emboldened he raised his wand and shouted the spell. Harry Potter keeled over dead and Voldemort gave a cackle before pulling out the Time-Turner and returning to his own time. He was confronted by Lily Potter, dressed in a white robe that hid her eyes, various daggers and other muggle weapons strapped on her back; her wand was pointed at his face.
"Crap" he sighed.
Yes, I realize I play too much Assassin's Creed...
