The moment the car stopped, I threw the door open and ran toward the sliding glass doors.

The lobby was warm, smelling of pine-scented disinfectant and old floor wax.

The receptionist looked up from her desk, her eyes wide with surprise.

“Miss, you can’t run in here,” she called out.

I ignored her and headed straight for the bank of silver elevators.

Charles was right behind me, his heavy boots echoing loudly on the polished linoleum.

I pressed the button for the fourth floor repeatedly, my finger shaking.

“Calm down, Emily,” Charles said softly, placing a hand on my shoulder. “We are here now.”

The elevator doors slid open with a soft chime.

We stepped inside, and the doors closed, shutting out the lobby.

I watched the floor numbers light up on the panel.

One. Two. Three. Four.

The bell rang again, and the metal doors parted.

The hallway of the fourth floor was silent and dimly lit.

Shadows stretched down the corridor from the nurse’s station, which was completely empty.

“Where is the staff?” I whispered.

“Look,” Charles said, pointing at the floor.
