Author's note: This will be a collection of stories about some of the mysteries that I made up that would be solved by Gwen and Merlin; the low-key detectives. If you all like it, then let me know and i'll continue writing it. Also, I'm from the US so apologies for any US mannerisms.
Disclaimer: I do not own Merlin or anything that is recognizable from the show.
Their detective work took off after they exposed the truth behind the Witchfinder. Though, "took off" might be a bit strong but Merlin did like a more positive outlook. Before the Witchfinder, he would just find things for people very quickly, with or without magic. A noble woman calling him over while he was already running late with Arthur's breakfast was inconsolable about her missing necklace. Merlin promised her he'd be right back, he ran (without tripping) to Arthur's chambers, ripped open the doors with much force (and a little bit of magic) which caused Arthur to fall out of bed in an attempt to defend himself from the potential threat of Merlin. Merlin placed the tray onto the table shouted a "Sorry Sire!" over his shoulder as he left, slamming the doors behind him before Arthur could even get a word in edgewise. He figured that Arthur was definitely awake after that and could manage for a bit. He made it back to the noble woman calling from down the hall "Where did you last have it?" which he knew was inappropriate of him but the Lady seemed faintly pleased with his eagerness.
It turns out when they retraced her steps she had accidentally dropped it behind her vanity.
She had been leaving soon to return to her own estate with her father Lord Evans and she was pleased that Merlin found it. She even offered for him to come work for her which he declined quickly and politely but not to potentially ruin her good opinion of him, he had offered to carry her remaining things down for her which she accepted. On the way down, every person she passed she spoke of how Merlin found her necklace for her which embarrassed Merlin greatly. When they were outside and Merlin loaded the carriage with her bags was when Arthur showed up, fully dressed and angry. But again that day Arthur was doomed not to be able to speak because before he could yell at Merlin, Lady Katherine was singing his praises and apologizing for stealing Arthur's manservant for the morning. Her rapid speech seemed to make Arthur weary and he wisely kept his mouth shut.
"Oh! I haven't really given you a reward, have I?" Lady Katherine said. "Name your price, Merlin."
Merlin thought for a moment before giving her a mischievous grin which she returned. "Just spread the word, that I'm the best finder in all of Camelot!" He said.
Arthur groaned while both servant and Lady laughed.
"You know what, I think I will. I hope your business picks up soon since you have such a well-established benefactor." Lady Katherine giggled. She then bid her farewell to both Merlin and Arthur as she climbed into the carriage. When she was out of sight, Arthur grabbed Merlin and dragged him back towards the castle while saying
"Finding necklaces now, Merlin? As if I needed more proof that you were a girl? Come on, you have chores to do."
The experience with the witchfinder only cemented one fact about Merlin and Gwen. If there was a mystery to solve, you went to them. The heads of the Camelot Detective Agency.
This is just a little introduction, it's not the greatest thing you'll ever read and who cares if "Detective Agency" is a bit too modern for the times. I'm rolling with it.
