You've been missing nearly a year, Ginny, my dear. There has been a death in the family. Not a person, don't fret. But Scabbers was brutally murdered by Sirius Black, of all people. Why he broke out of Azkaban to murder our family pet, I will never know. I suspect we never will. He has not been heard from since. Everyone is fine. Ron was there when it happened, and the only person he will speak to about it is Professor Dumbledore.

...

Harry, once you return, you will be interested to know you have a godfather. His name is Sirius Black, and he's been in Azkaban since he was wrongfully accused of betraying your parents, and killing a street full of Muggles. He… is not yet capable of casting a patronus, but I myself am working with him. I am sure he will contact you shortly. Give my regards to Ginny, wherever you may be. Oh, and Gilderoy, I suppose.

...

It's your thirteenth birthday, my girl. Your mum and I have been missing you. We miss you every day, but this summer has been particularly hard. We had the chance to go to the Quidditch World Cup – I know how much you would have enjoyed it. We – we didn't end up going, no one felt up for it.

We have searched by all means that we know of, and still we cannot find any trace of you. It is… unbelievable to me that you will remain missing forever…

How has it been three years since I've seen your face?

We miss you, Ginny! We learned how to make patronuses just for you. Deuced hard, that was. We promise not to make too much mischief with them.

I confess, I do not know how this has happened. I do not understand how two children and a professor disappeared, leaving behind what I assume is a slaughtered Horcrux. You will not know what a Horcrux is, Harry… but I would have sworn – never mind.

Harry, I need to tell you about a prophecy made about you… about Lord Voldemort… before you were born…

GINNY, WHERE ARE YOU? COME HOME!
