Dear Mr. Castle,

I wish Derrick Storm was real. I wish someone existed who actually did their job, and solved crime. And although an international super spy wouldn't necessarily care about a single case in the NYPD archives, it would make me feel better knowing that someone was out there searching for justice.

You see, my Mother loved your books. I can still see her, sitting by the fire, her case notes shoved aside with your book in her lap. I remember her breathing sharpening as she got into it, her eyes moving fast over the pages. And before I left for school again after the holidays, she tucked Hell Hath No Fury in my carry on, a sticky note on the cover telling me to call her when got home. Now my Mother only exists in my memory, her life taken from her well before her time by some asshole in an alley with a knife. It's been a few months, and the sting is still there, but the pain doesn't knock me over like it used to. If anything, I have your books to help with that. I started reading them after her funeral. I liked to imagine how she would feel, what she thought might happen next, how believable she thought any of it was. It was a way for me to feel close to her again, and for that, I truly thank you.

The detectives assigned to her case don't seem to care. They never collected her case notes, we had to drop off the hate mail she received from the few clients she ever lost, and they seem to be annoyed whenever we call. They keep offering this idea of what happened, and disregard any facts that point in another dimension. And instead of getting justice, her file is sitting on a shelf gathering dust. Derrick Storm wouldn't stand for this. Derrick Storm would follow this case wherever it went, no matter how unlikely. So thank you. Thank you for a character who always sticks up for the little guy. Thanks for creating someone so eager to find the truth. I don't think you understand just how important he is.

Sincerely,

Katie Beckett

A/N: A family friend is doing this thing called incowrimo this year, in which she writes a letter to someone every day this month. Since Castle literally wrote Kate a book, I thought it would be interesting to see what types of letters Kate writes to him. To be honest, I've been fighting with some depression in the last few weeks, and this might just be the project to pull me out of it. I can't promise one a day, and I have catching up to do, but I will do my absolute best to churn some of these out. I hope you enjoy!
