The British Red post box. So I noticed most Christmas cards in the shops have the red post box on them in Wales so had to get one in somewhere. A Christmas bauble appears on Melissa desk in the shape of a royal mail red post box. December 5th. Callen's point of view.

It's 6:25 when Sam, Melissa and I enter the mission. Melissa caught a ride in with us today instead of with Nell. I don't know why maybe she fancied changing things up? It was nice to have someone to chat to that isn't Sam on the way in though. We were all laughing at how scared Eric got when he admitted he was behind the candy cane joke and Melissa pretended to be angry. We all walk into Ops laughing when Hetty appears before us. The sunlight is streaming in through the window casting shadows everywhere.

'Good morning.'

'Morning Hetty. Is that a new brooch I spot?' Melissa greets her back just as cheerfully. I notice the brooch now that Melissa has mentioned it and then look at Sam who shrugs.

'It is Miss Createn. How observant.'

'From Migs I'm guessing. It's her style.'

'Your deduction is correct.' Hetty nods as she lets Melissa past. I quickly follow.

'It's charming…' Sam automatically comes up with something nice.

Melissa stops dead in front of me in the bullpen entrance and I place a hand on her shoulder to stop myself bumping into her.

'What's up?' Sam asks peering over my shoulder as I follow Melissa's gaze to the strange red object placed on her desk.

'What is that?' I ask.

'Not sure. I think it's a Christmas ornament for a tree.' Melissa picks up the offending item and carefully studies it, holding it by the red ribbon attached. I'm sure there's a look of recognition in Melissa's eyes as she studies it.

'What is it an ornament of?' Sam enquires asking the question that I would have asked if I wasn't busy watching Melissa.

'It's a post box.'

'No a post box is square and blue not round and red.' Sam comments quickly as she passes it over for him to look at. He quickly passes it to me. I think he's scared he'll break it. It's porcelain, easily breakable but the paintwork is amazing, it's so detailed. I'm amazed by it.

'Royal mail post box. British postal service.'

'Oh British!' I laugh at the tone of voice Sam uses. Sam sits down at his desk. I sit on the edge of her desk.

'How do you know that?' I query trying not to laugh or sound surprised.

'I lived in Wales for 13 years G. I used to see at least 1 of these daily on my way to school, probably passed dozens of them.'

'So where did it come from?' I pass the delicate item back to my partner who has sat down at her desk. She looks at it as she speaks.

'I don't know G but it looks awfully similar to one my granddad used to have so I will need to speak to Granger find out if he knows anything.'

'Your granddad, he's British?' Sam looks at her.

'I'm British. Half British, half American.' She answers looking up from the ornament. 'Mum was British, Dad is American.'

'So what do you classify yourself as? British or American?'

'I classify myself as Melissa Louise Createn G, that's all you need to know.' She responds placing the ornament back on her desk and grabbing out a file from her inbox. I leave the subject be. Melissa's tone of voice and response told me all I need to know.
