Rule #4 of the 12th precinct's Homicide Division: If you set foot in the precinct with donuts, you absolutely must bring one immediately to Captain Montgomery. If not, he WILL hunt you down.

I do NOT own Castle.

For anyone wondering, there will be more Caskett related rules soon. Just that most seem to revolve around the boys more right now.

Also, these aren't really in any specific timeline. And they don't really flow one after another. Just little glimpses into the precinct life. XD


Beckett, Ryan, and Esposito all jumped when the Captain slammed open his office door, hurrying out of his office with his nose in the air. The Captain sniffed the air a few times in each direction, before taking off towards the elevator that had just opened to reveal Castle carrying a pastry box.

"Hey there Captain," The writer said as Captain Montgomery stopped right in front of him. "I got us some donuts, figured we could use the-"

Without a word, the Captain snatched the box from Castle, quickly opening it and taking a donut before retreating back into his office with his prize.

"-sugar...Okay, that was a little weird." A now very confused Castle walked into the bullpen to see that though the rest had been watching that scene, they weren't surprised at all.

"So...Anyone want to explain what that was about?"

"Captain likes his donuts." Was all that Esposito said, as if that explained everything.

"I can tell."

"Oh that was nothing," Beckett walked over to the writer and snatched a donut from the box. "You should have seen the time Karpowski brought one back after her lunch break, not even thinking about bringing an extra one for the Captain. She hid in one of the storage rooms on the basement floor, but he still found her and 'confiscated' the donut."

Well, at least now he knew what to do if he ever made the Captain mad.


"No, I refuse detective! He nearly blew up the whole damn precinct! I'm not letting him back in here."

"But, sir..." Beckett tried to get him to change his mind, but he was not swaying even a tiny bit.

She did her best to try and get him to let Castle shadow her again for a few minutes longer, but nothing was working.

Just as she was about to give up, there was a knock at the office door. It was a delivery guy.

"Captain Roy Montgomery?" The guy asked and when the Captain nodded, he handed over a huge box.

"Sign here, please." As soon as he had his signature, the delivery guy was gone, leaving Beckett and the Captain with the box.

"What in the world..." He muttered as Beckett watched him carefully pry open the lid of the box. His eyes lit up like a kid seeing a ton of presents under the tree on Christmas morning and his face split into a Cheshire cat's grin.

"Okay, you tell Castle he can come back. But! If he ever does anything like that again, it's going to take a lot more than this to get back into my good graces."

Beckett just blinked at him for a minute, before deciding not to look the gift horse in the mouth and headed out of the office to let Castle know the good news, leaving the Captain alone with his giant box of donuts.
