Sincerely, Your Shadow #1

It was quite a normal day like any  other.  I reluctantly headed to our mailbox.  Since our dad is a famous author, he receives a ton of letters.  So mail duty is my least favorite chore.

Like every other day, I pulled out all the letters.  A black one fell.  As I picked it up, I realized it wasn't for my father, but for me.  I looked again.  It said in fancy letters: Abigail Uhbandont.

I gave the rest to my father and hurried to my room.  Carefully, I opened the envelope.  The letter was like none I had ever seen.  Like made of parchment.  Eagerly, I read,

My Dear Abigail,

Times have been tough, but finally, I have found you.  Your parents did an excellent job keeping you safe and you should be happy you didn't stay with those other terrible guardians that almost lead you to your death.  No need to worry now, though.  I've got you.  You'll be safe now.

Sincerely, 

Your Shadow

P.S. Do not tell anybody of this letter.  There are more to come.
