I thought about it a while ago and thought I should do something with it! I hope you enjoy it! In the next chapter(s) will be more mystery but every story needs a begining.

Have fun!

and: I don't own any of Castle except the love I have for it!

It was a beautiful but early Friday morning in the middle of the holidays but NYPD Detective Kate Beckett had to work. Kate Beckett woke up in her new apartment which was her first night there, of course, was staying with lanie nice but the feeling again to wake up in her own apartment felt very good. She stood up and did her morning ritual. She closed also for the first the door of her new apartment and she went on her way to work. She came very early to the Precinct as always and walked straight to the espresso machine. The espresso machine reminded her always of Castle. Why had he not take that thing with him when he leaved. Then she wouldn't have every morning that feeling in her stomach. It was the sense of lost, grief, and the worst of being to late. It had been weeks, maybe months ago, since Castle ran away with Gina. As usual, there was nobody at the Precinct even the Captain wasn't there. Her coffee was finished and she walked to her desk. When she sat down she saw a note. She thought she had another case. She took the note and opened it:

You Can Fall From A Mountain,
You Can Fall From A Tree,
But The Best Thing You Can Do
Is Falling In Love With Me!

Dear Kate,

It's probably too late but I miss you.
I want to see you.

Tomorrow you're mine!
I've already planned the hole day,

So you can't cancel it!
Tomorrow at 11AM in Central Park.
Don't worry I am there, you see me.

It'll going to be so much fun!

Don't for get it!

-X-

What should I do? Be professional ... pretend that there happened nothing.Shit I have to ask if I can get tomorrow off.I do that if Montgomery is here. Kate thought. She reads the letter over and over again. She was so lost in thought that she didn't even knew when everyone arrived. She kept staring at the letter.

"You okay?" Asked Esposito

Silence

"You all right?" he asked again

Silence

Then he saw the note in Beckett's hand. He waited a few more seconds and then took it out of her hand. At that moment she looked straight up.

"What's this?" he asked when he read the letter.

"Nothing. Gif it back!"

"Aha, I see what's going on"

"Oh yeah?"

"Yes, you have a got a love letter from a secret admirer.

"No! I have not!"

"What's going on?" Ryan asked when he walked to his colleagues.

"Beckett has secret admirer"

"Do not be childish and give me back my letter!"

"And guess who was not there tomorrow," he said, holding the letter up.

"Give it back!" This time, Beckett said in an angry tone

"I guess, it's Beckett" said Ryan

"Well guessed, you should read" Esposito said and gave the letter to Ryan. Beckett was just too late for him to grab the letter and Ryan walked away. Captain Montgomery came out of his office because of all the noise.

"You Can Fall From A Mountain, You Can Fall From A Tree, the best thing you can do is falling in love with me! Romantic! "Said Ryan and nodding head.

"Do not be childish and give it back," said Kate but Ryan continued

"Dear Kate," He said, glancing away from the note "It's probably too late but I miss you. I want to see you." Kate came closer and Esposito ran quickly behind Ryan and took the note and read trough.

"Tomorrow you're mineI've already planned the whole day, So you can't cancel it! Orders he, I did not know you liked that, "said Esposito in a sly way and continued "Tomorrow at 11AM in Central Park. Don't worry I am there, you see me." She was so close to Esposito that she could almost take the letter, when he folded it up and frisbeede it to Ryan, how read through "It'll going to be so much fun! Don't for get it! Oh, who could that be? And a X in the end. How romantic" he said sarcastic

"Give it back!" To her great surprise, he gave it back. After a few seconds she understood why, Captain Montgomery had come out of his office and didn't look happy.

"Kate, can I talk to you for a second?" he said and and he walked into his office without an answer.

"Thank you" she said angrily to Esposito and Ryan before she walked into the office

"Kate, you're my best detective and I thought you knew and everything that you would come to me"
"But ..."
"No, now I am here to talk" he said "What was that there? The whole scene? "
"I don't know, I was here really early when I saw this letter and before I knew Esposito took it out off my hand"

"Okay, I don't want to read it but I heard that the man wants to see you tomorrow."

"Yes"

"Do you want to see him to? "

"I don't know."

"You know you are always free to ask me everything right"

"Yes"

"But if it goes about days off you have a least to ask it one week before, right"

"Yes"

"Then you know that I can't give you free tomorrow"

"But Captain"

"I can't do it how much I would like"

"But I really need to know how it is" Kate said

"Why?"

"I never had something like this. I never had a secret admirer"
"l under stand but rules are rules"

"I know but I have almost never a day off"

"I know and I admirer you for that"

"Okay, I think I know who it is and it means so much for me if it's me so please, I beg you, give me tomorrow free" she thought about Castle and Montgomery knew she thought it was him.

"Okay but only because you haven't had a day off in a while and because you want it so much"

"Really?"

"Yes, and I take care of the boys tomorrow" he said and winked at her

That made her laugh "Thank you"

"Work hard today and have fun tomorrow" he said with a smile and with that she walked out of his office.
