Alice Prewett stood in library of the Potter household listening intently to the loud noises of wand fire and the screaming rage coming from what she guessed was James Potter. Although she knew that the room in which she resided was safe from the sight of the attacker the pure flood of fear within her could not be contained. As she stared intently at the doorway – an open archway – the only thing hiding her from the figure now present within it were Lily's wards. It was clear that at any moment those wards would fail as the figure of Voldemort ascended the staircase. Once he was out of sight the only thing to be seen was the slackened grip of James hand around his wand on the floor beside the opening.
As tears streamed down Alice's face she cast a disillusionment charm over herself and followed the footsteps of Voldemort himself, being careful to make no sound. Lily's pleads of mercy and compassion could be heard at this point however the sound of Voldemort's exclamations of laughter at her 'pitiful fight' seemed to draw the situation into reality – he was not going to spare her.
"Did you really think that I, the most powerful wizard of our time would allow the child of a mud blood, no less, to hold a power greater than my own? No." the cold tone of Voldemort's voice thrilled through Alice as she stood helpless in the doorway to Harry's room as he carried on "No! Your friend Wormtail was quite gracious in advising me of your presence in Godrics Hollow and now, here we are." Voldemort made a great sweeping arch through the air shouting "Avada Kedavra" in his shrill, chilling tone. As his spell met Lily's chest she was thrown sideways leaving Harry's crib exposed, one solitary tear made its way down Alice's face.
However with a nod of determination Alice lifted her wand in sync with Voldemort and as he whispered the words "Avada Kedavra" her invisible shield hit the green light directly and in the process creating a blinding blue explosion to erupt around the room. The only sound was the whirring of the sneakoscope in the downstairs library and the crackling of the fires now erupted around the crib of Harry Potter.
The sound of a shrieking baby reached her ears. Alice groaned as she woke from what she envisioned as a nightmare, however she was quick to realise it had been real. Harry was lay down in his crib yelling for his mummy, his limbs flailing and his face bright red from excursion. There appeared to be no sign of Voldemort as Alice approached the crib to retrieve Harry; however Lily was lying on the floor with no life in her eyes but an expression of determination on her face, she was not going to let Voldemort harm her child without a fight.
It would seem that Lily's own perseverance and Alice's intervention saved Harry from his fate, though a lightning bolt cut had appeared upon his forehead but it had apparently sealed itself. Alice ran down the stairs away from the room and past James into the library, the alarm had to be sounded. She lay harry down on the sofa and approached the fireplace grabbing a fistful of floo powder along the way. As she threw it into the flames she called out the familiar name of the Burrow, which at this moment she knew held several aurors and friends of Lily and James. She thrust her head into the green flames.
"Molly! Molly!" she was yelling at the top of her voice, able to see upon the wall opposite that her own hand on the clock was pointing at mortal peril. A short plump woman came into view clutching tightly to a struggling one year old.
"Oh Alice, I'm so glad you're alright!" she exclaimed blotting her face with an already sopping handkerchief.
"Yes, Yes I'm ok but Molly are Sirius and Remus there?' the desperation in her voice may have been what prompted the devastation on Molly Weasley's face, she was piecing together the situation, reading her sister like an open book. As a trainee Auror Alice knew not to disclose too much to Sirius on this occasion because he, as her mentor, had told her that anyone too close to the people involved are to be treated as loose cannons, they are to be told enough but not every detail in the immediate telling.
"Remus, Sirius I need you to bring Wormtail in. I will meet you at the office, be quick it's not safe." With this Alice withdrew her head from the fireplace, snatched up Harry and apparated to the ministry of magic.
