As the day pass on by until very late afternoon, inside a dark lit room sat a dark gray stallion in his flour white shirt and black tie; his brown fedora blocked his crimson eyes and the white diamond shade on his forehead. He lets out a long boring yawn, lifted his fedora up a little to gaze upon the small letter on the desk. He sighed as he took the letter and threw it to the waste bin next to his dark wooden desk. The room covered with a thick layer of silence, he could hear his own breathing if he listen carefully; it have been days without anything interesting going on. A soft knock on the door broke away the silence; he turned to it with excitement in his eyes:

"Come on in." he said to whomever at the door.

The door open, which the stallion feels disappointed when he saw a young filly with red mane and a pink bow on her head wearing a blue overall.

"Excuse me," the filly said in an obvious southern accent, "is it the Diamond Eyes of Truth?"

"Let's me guess, one of your pet is missing right?" he lean his head over his hoof.

"G-Gosh mister, how'd ya know? His name is Mr. Scratchy, and I can't seem to find him anywhere."

The stallion let out another sigh, "I'm sure he's up in the tree somewhere in your neighbor's yard. Also, why are you all by yourself? Isn't your family helping you search?"

"Ay can't. My sister is working in this big building with all kind of creepy stuff, and my big brother is busy with his chore."

The stallion sighed, "tell you what: I am currently busy with another missing pet, but after it's over, I'll come over to help you find Mr. Scratchy. In the meantime, you can go check the nearby trees for him, okay?"

The young filly nodded her head, "Thank you so much mister. You can come over to the Bugzy Farm near the wood."

The stallion gave her a gentle smile, "I hope you find him."

The young filly left the room; after she's out of sight, the stallion sighed, "why is all missing pet case always my department?" he put his brown fedora back over his eyes and lean back on his chair, decided to take a small nap until something else knocking on the door. Moments later he heard hoof-steps in front of him; not holding his hope this time, he sighed and said:

"If it's another missing pet, I'm very busy." He said.

"You sure look busy, Diamond."

Diamond recognized that voice; he lift his fedora and saw the lavender unicorn staring at him with a smirk: "Star?" he asked, "Holy cow, how have you been?" he walked and give her a short friendly hug, "it have been, what, weeks?"

"Months, Diamond."

"Wow, time sure flew by fast. How are you?"

Star greeted him in her silk black coat over her white classy shirt and a small red bowtie around her neck. Diamond could tell she's doing really well, and she rather looked more professional than the last time he saw her.

"I'm fine, thank you," she looked around Diamond's room, "I see you still have the old private eye business."

"Yeah," Diamond replied, "business hasn't been booming lately; you know, always with pet missing case. So…what are you doing now?"

"I'm an assistant for a professor at the Equestria's Historical Archive. That…actually the reason I came here."

"What happen, does a skeleton remain of a dog have gone missing?" he joked.

Star looked at him with a serious looks; this gave him enough clue this isn't a joke, "Oh, sorry. Old habit dies hard."

"The professor that I work for, Professor Cipher, is missing. I need your help to find him."

Diamond sat back behind his desk and lean toward her, "are you sure he didn't got lost somewhere?"

"Diamond, he's literally live there himself; I'm sure he'll find his way in there quicker than you could find your lunch."

Star then began to explain to him about the situation: how she heard the professor cry for help and how his office turned upside-down as if someone was looking for something. She also told him what he was doing before he disappear, explaining to him it could be the reason someone might taken him.

"Star," Diamond reassured her, "you're over-thinking it, as usual. I'm sure he's fine somewhere. Not everything always leads to some conspiracy of some sort, only most of them."

"Well whatever the reason is, I need your help. New artifacts just arrived this morning, and the curator needs him to authenticate them before she gives them a proper display."

"What about you? I'm sure you can authenticate them for her, being his assistance and all."

"I would love to, but I'm still a bit rusty at it. I wouldn't come to you if I'm desperate."

Diamond stood and looked out the window; he feel a bit uncomfortable about this, 'being with her again after…' he shook his head from the thought, "I don't know Star. I really wasn't looking for another missing person case again. Don't get me wrong, I want to help you, but…it's complicated."

Star looked a bit disappointed from his answer; however she thought of an idea: "I understand. I guess I better return and take a look at that weird stuff I found in the room then."

Diamond's head jerked up when he heard the magic word: "Weird? What do you mean by weird?"

"Oh you know, something was left in the scene, but I've never seen it before so I'm really wants to study it soon."

She was about to leave when Diamond flew up and stood in front of her: "you're not just saying that for me to get interested, right?"

"I wouldn't lie about it."

Diamond has a moment to think about it; somehow this case sound more interesting than before. He couldn't help it; missing pony is one thing, but if Star tell him the truth, and she always does, then this mysterious stuff that she found make him very intrigue.

"Fine, you win; I'll help you find your precious professor, just because I want to know what 'weird thing' you found, so don't get any wrong idea."

"Who said anything about wrong idea?"

Diamond can't find anything to reply to that. He just put on his big light brown coat over his shirt and flew slowly out the room. Star shook her head lightly with a smile, "guess something will never change."
