The day was sunny at the university. Our campus was pretty far from town, with forests all around it and a few old mills spread out nearby. For the most part, it stayed quiet, apart from the birds. Their songs came from the trees throughout the day, and in some way the campus never seemed complete without hearing them.
By the time evening came, students were already making their way home. I threw my bag over one shoulder and headed toward the library. No, I wasn’t there to study. I was there to see Charlotte.
Charlotte was my girlfriend, and she was really into books. Since our classes were in different parts of the university, we didn’t get to see each other much during the day. So the library turned into our meeting spot. Pretty much every evening after class, I’d find her sitting there with a book in her hands.
She could go on forever about whatever she was reading, especially fantasy stories. She’d tell me about the characters, the places they went, what happened to them, and why certain ones were her favorites. Half the time I had no clue what she meant, but I still enjoyed listening to her.
After the library, we’d usually grab coffee from the vending machine outside. Around most people Charlotte was quiet, and she only had one or two close friends. Margaret was one of them, I think. Or at least, I’m fairly sure her name was Margaret.
That was basically our routine. Let’s meet at the library, grab some coffee, find a quiet spot near the canteen, and sneak in a few kisses before we head off on our own. After we got home, we kept talking through texts and late-night chats. It’s nothing complicated. It’s just us, doing those same small things every day.
Something had shifted by the time Thursday came around. The normal evening group was getting smaller, and I spotted Charlotte walking out of her classroom roughly twenty minutes late, with her backpack slung over one shoulder. Rather than walking over to me, she paused by the air-conditioning unit and checked something inside her bag. When I went over, she kept her hands tucked in her jacket pockets and avoided looking at me. She looked pale, and the edges of her eyes were red.
“What happened?” I asked.
She paused for a moment before she finally told me what had happened with Margaret. Margaret had failed her second midterm and was stressed about academic probation, so she’d caught a rumor that Professor Rodri stored copies of the semester practical in a drawer that was locked. Once the secretary had gone, she talked Charlotte into going with her to check the room.
“We never even got the drawer open,” Charlotte said softly. “The door wasn’t locked, but Rodri was still in the back room. He came out while Margaret was standing right next to his desk.”
I just stared at her. “He saw you?.” Charlotte finally raised her eyes to me.
“He saw Margaret.”
By Friday evening, the university had pretty much cleared out for the holiday weekend. I was on my way to the south gate when I saw Margaret walking by herself near the bus stop, her coat wrapped tightly around her against the cold.
“Margaret, where’s Charlotte? I thought the two of you were finishing up the work together.”
She paused and glanced away for a second. “Rodri told me I could leave early. Charlotte stayed behind.”
I frowned. “He made her stay?”
“She said she would finish the rest.”
“You just left her there alone?” I asked, unsure.
Margaret let out a sigh. “She told me to go. I didn’t want to get into another argument with Rodri.”
I took out my phone and called Charlotte. It rang a few times, then went to voicemail. I tried once more, but nobody picked up.
“When did you last see her?” I asked.
“Roughly an hour ago. She was at Hartwell Hall, down in the lab on the lower floor.”
Before I could get out another word, she rushed off toward the bus. I just stood there and watched it vanish down the road, my phone still in my hand. Something felt off.
I spun around and started back toward Hartwell Hall. The campus had gone strangely quiet by now. Nearly all the lights in the buildings were off already, and the wind blew through the trees beside the empty walkway.
At the far end of the science complex stood Hartwell Hall. When I got to the entrance, I figured the doors would be locked.
They weren’t. I pushed one open and walked in. The hallway was dark and chilly, with just a dim light coming from somewhere below.
“Charlotte?” I called out.
My voice vanished into the empty building. I held my phone tighter and began walking toward the basement stairs.
I took my phone out of my jacket. 6:53 in the evening. I gave Charlotte another call. It rang three times, then went to voicemail. I gave it one more try, but still nobody picked up.
