A week passed since Nyx's first case as a detective. During that time, Nyx read about many different things, about 200 different books on various subjects. She also occasionally checked on Trixie and Daydream every other day.
She had also done something else. Twilight had used her bits to purchase a building for Nyx to set up her new detective agency. It was a medium sized building with multiple rooms, a three sided open/closed/on a case sign in front, everything that she would need as a detective, and a large sign over the entrance saying "Detective Nyx's detective service" on it.
"This is my new detective agency!?" Exclaimed Nyx, excitedly. "I love it. Thanks for buying it for me, mom."
"Of course, sweetie." Replied Twilight. "Now go on, your new job is waiting for you."
Nyx hugged her mother before galloping into her new detective agency.
"My sweet daughter is growing up so quickly." Said Twilight with tears of joy in her eyes as she walked away.
Meanwhile, Nyx was looking around her new detective agency. "This is so awesome. My very own job."
Nyx then heard the door open behind her. She turned around to see Apple bloom, Sweetie belle, and Scootaloo
"Congrats Nyx." Said Apple bloom.
"I like your new detective agency." Said Sweetie belle
"You're job is so cool. You'll have to let me join you sometime." Said Scootaloo
"I will Scootaloo. So, you guys want to hang out?"
"Sure." They all said together.
"I'll race you to Sugarcube corner after I visit Rarity for something."
"What do you need to visit my sister for, Nyx?"
"I want to get some detective clothing. A detective doesn't usually not have one."
"Interesting. We can start racing from there."
The four fillies trotted towards Rarity's house very quickly, arriving three minutes later.
"Rarity?" Said Nyx, "Do you think that you could make me a detective hat and suit?"
"Certainly, darling. I'll get started on it right away. It'll be ready in a few hours."
"Could you drop it off at my detective agency? Just walk right and keep walking until you find it."
"Sure thing, Nyx." Replied Rarity
"Thanks Rarity."
Nyx and the CMC left Rarity's boutique and spent the rest of the day together doing many different activities until they all went home for the night.
The next morning, everypony was waking up and getting ready for work.
Nyx woke up, had a quick breakfast, then left to go to her detective agency after saying goodbye to Twilight and Spike. She flew through town towards her detective agency.
When Nyx arrived, she flipped her open/closed sign around so that the "open" side was facing the window. Then she walked into her office room and noticed the coat and hat on the desk. Nyx levitated the coat and hat and put them on before she sat down at her desk, which had a phone sitting on it.
A few minutes later, the phone started ringing. Nyx quickly levitated it to her ear and answered the call
"Hello, this is Nyx's detective service. How may I help you?"
Nyx, I need your help with something. I can't find Rainbow Dash anywhere.
"Woah, calm down Scootaloo. I'm sure that Rainbow dash is just busy working."
She's not though. I already asked everypony that she works with, her friends, and my friends. None of them have seen her for 5 full days.
"Don't worry Scootaloo, Detective Nyx is on the case. I'll find Rainbow dash and bring her home."
Thank you, Nyx. I'll promise that I'll make it up to you.
"Scootaloo, meet me at Sugarcube corner in 15 minutes. We'll talk about this while we have some cupcakes. I'll pay for it."
I'll be there. See you then, Nyx
Nyx levitated her saddlebag on her back and put her magnifying glass, one of her notebooks, a bag full of bits, and several plastic bags for evidence inside
Nyx walked towards the exit of her detective agency and flipped the sign to where "on a case" was facing the window, then she walked out and headed towards Sugarcube corner. She got there exactly when she said she would be, and Scootaloo came on her scooter a few seconds later
"Good. You're here." Said Nyx. "Come on, we have important things to discuss."
Scootaloo followed Nyx inside Sugarcube corner, and the two of them sat down at one of the booths.
"Hey, you two." Said Pinkie, "Want any treats?"
"We'll have a plate of cupcakes, please." Said Nyx
"Okey-dokey-loki." Replied Pinkie, "They'll be out shortly." Then Pinkie rushed into the kitchen
Nyx pulled out her notebook and prepared to ask Scootaloo questions. "So, Scootaloo, when was the last time that you saw Rainbow dash?"
"It was 5 days ago, around 1:30 in the afternoon."
"What was she doing during that time?"
"I think that she was flying towards the Everfree forest."
"Did you ask her why?"
"No, I didn't think to."
"Did you try to chase her in?"
"I did a little, but then got scared by Timberwolves."
The fillies suddenly heard Pinkie next to them. "Hey, I overheard your conversation. But I don't have any information like last time. Maybe you should check the border of the Everfree forest after your cupcakes." She said, holding a plate of cupcakes.
"Thanks Pinkie, for the cupcakes and the advice." Said Nyx, giving Pinkie 12 bits. Nyx and Scootaloo ate the cupcakes until there were only 4 left.
While they were eating, Scootaloo asked, "Hey Nyx, could I join you on your investigation. Please?"
"I suppose. Sure, you can help me." Replied Nyx
"Thanks, Nyx."
"But the second that it starts getting dangerous, I'm sending you back to Ponyville."
"Okay." Replied Scootaloo. Then the two of them left Sugarcube corner to continue investigating.
Scootaloo followed Nyx over to the edge of the Everfree forest, hoping to find something that could help them
"Okay, you go look left, and I'll look right." Said Nyx to Scootaloo
"On it."
The duo searched and searched for an hour. That was when they found something
"Hey, Nyx. Over here." Said Scootaloo.
Nyx rushed over and noticed a blue feather, though it seemed to have some kind of magic covering it.
Nyx put the feather in her bag, before looking toward the path that led into the Everfree and noticing more blue feathers covered with magic.
"Hmm. It looks like we're going to have to visit the Everfree forest. Come on Scootaloo, we've got a pegasus to find."
