City Birds

Sans pulled into his driveway and slowly got out. He looked up at the house and saw that Pap’s light was on. He must be home.
He walked to the door and opened it. It was unlocked thankfully, and he closed it behind him. He took off his hat and hung it on the coat tree. He could hear Pap’s TV blaring, but it was likely that the was asleep. He woke up really early because he had to investigate a drug dealer’s house. They were charged with murder and attempted murder along with the drugs.
Their job was complicated. He kicked off his shoes and put them on the shoe rack. He loosened his belt as he walked up the stairs.
“Papyrus?” He called quietly as he peeked in his brother’s room. Pap was, as Sans suspected, asleep. But he was in the chair that faced to door, as if he was waiting for Sans to get home. He was still wearing his coat and shoes, but he was leaning his cheek bone on his hand.
Sans’ expression softened and he gently closed the door. He walked into his room and put his belt neatly into his dresser. He stretched and looked around. Nothing seemed out of place, so he began to change into his lounging clothes. He was about to pull on his shirt when his phone rang. He picked up and answered, “This is Sans.”
No answer. Just… fuzz? Sans was extremely puzzled. “Hello?” Then there came an altered female voice.
“You’ll never know who she is.”
“Who is this?”
“She will never reveal herself to you.”
“I demand to-”
“She will die before you get the chance.”
“Wha-”
Click.
The phone was hung up. Sans stared at it, but he couldn’t read the number. It was glitching, and then the phone turned itself off.
Sans sighed in frustration. He turned it back on and saw that all his call logs were deleted.
Then there came a knock on the door.
“What is it?” Sans answered and Papyrus opened the door. He was in shorts and a black tank top with his usual slippers.
“who was that?” he asked as he leaned against the doorframe.
Sans shook his head. “I don’t know.”
“what did they say?”
“That I’ll never know who “she” is. That she will die before I get the chance.”
“that’s strange. i got one like that too.”
Then Pap’s phone rang. He picked it up.
“hello? ... yes, this is papyrus….. oh, hello captain…. a strange call? yeah, sans and i both got one. why do you ask? …. every single one? this is odd…. no, ma’am, just a few sentences. started talking as soon as we said “hello.”..... what did it say? it said “you’ll never know who she-”.... yes ma’am, it was a female speaking…. the number?”
He looked at Sans with expectancy. Sans shook his head and Papyrus continued, “no, neither of us did. it deleted all our call logs….. no, everything else is there…..”
He listened for a moment before pulling the phone away from his face and pushed the button to put it on speaker phone.
“Am I on speaker now, Detective Gaster?”
Neither of them liked hearing their last name.
“Captain, please… that’s our Father.” Sans said, feeling more nervous than he was before.
“My apologies, I keep forgetting. Detective Papyrus and Officer Sans, I have some very specific instructions.”
“We’re listening, Captain.”
“Good.” It was at that moment that Sans realized that her voice was worried. “All the phones here at the precinct blew up with the same recorded message. And I want you two to enjoy your vacation and not worry your tired skulls about this.”
“But Captain-”
“No buts, Sans.” Her voice was sharp and final. “I don’t want either of you getting hurt. You both are the only ones who got a call on their personal phones. That’s not a good sign.”
“i have an idea why we got the calls, captain.”
“And that is?”
“it’s because sans has met her in person, and they must be assuming that he would want to investigate into her identity, and since I am his brother she must think i have power to not let him. something along those lines.”
“I suppose that makes sense. I do not want either of you to try to find out who she is. I have a bad feeling about this call.”
“Why would we?”
“I know Papyrus is less likely; it’s mostly you, Sans.”
“Wha- Why-”
“Remember that time you spent two weeks finding out who a drug dealer really was after you got a gut feeling about her? You even found out that she was a transgendered male, and even went and found out about his parents-”
“captain, you said gut feeling. we-”
“I don’t have any time for your puns, detective.”
“sorry.”
“Captain?” Sans felt odd, and a little scared. “Why exactly do you not want me to find out her secret identity?”
The captain was silent. He could feel the hesitation in her voice as she answered, “Several years ago, before you two joined the police force, I had a young and intelligent detective. His name was Mark Finsh. He spent two months on his own case after he found out that there was another person, much like Nighthawk, was investigating his own stuff. He was exactly like her in that sense…”
She trailed off. Her breathing sounded quick, and labored with the obvious attempt to keep herself from crying.
Sans almost didn’t want to ask. “What happened, Captain?”
The tears weren’t hidden anymore, as her tiny sobs burdened her words.
“Some of the “hero’s” enemies found out what he was doing. They killed him in one of the most brutal ways imaginable…”
Papyrus gently interrupted, “you don’t have to describe it if you don’t want to.”
She gave a small whimper as her crying stopped.
“...”
“You liked him a lot, didn’t you captain?”
“Y-yes. Actually, he and I were dating outside of work…”
A heavy silence drifted over the room.
“I won’t even try to find out about her, Captain. I promise.”
