Patient 23

The knock at the door wasn’t particularly loud, but it made Elena jump nonetheless. “Hello?” she called out. No response.

Through the peephole, she saw only an empty hallway. She was about to chalk it up to kids playing pranks when a folded piece of paper slid under her door.

Her hand trembled slightly as she picked it up. The paper was thick, expensive-feeling, and had her name written in elegant cursive on the outside. Inside was a single sentence that made her blood run cold:

“I know what really happened to Patient 23.”

Elena sank to the floor, her back against the door. Patient 23. She hadn’t heard those words in over five years, not since the incident that had driven her from her prestigious position at Massachusetts General to this quiet research role in Seattle. She’d been so careful to cover her tracks, to bury the truth so deep that even she sometimes convinced herself it had never happened.

Elena stared at the note, her mind racing. Only three other people had been present that night: Dr. Chen, who’d retired to Singapore; Nurse Williams, who’d died in a car accident two years ago; and…

The sound of another paper sliding under her door made her scramble backward. This note was shorter:

“Open the door, Dr. Harrison. We need to talk about the experimental treatment.”

Elena’s throat went dry. The experimental treatment – her revolutionary protocol that had promised to save lives. Instead, it had ended one and nearly destroyed her own. She’d spent the last five years rebuilding her life, piece by careful piece.

Now, on an otherwise ordinary Saturday evening, it was all about to come crashing down.
