But Lily’s fingers tightened around his arm.

“I heard breathing,” she said.

Daniel tried to stay calm. He checked the curtain. He checked behind the door. He checked the bathroom window.

It was locked.

No one was there.

Still, something felt wrong.

The mirror above the sink was fogged, even though no one had taken a shower. A cold line of moisture slid down the glass like a tear.

Then Lily looked into the mirror and stopped breathing.

Daniel followed her eyes.

For one second, he saw it too.

A dark shape standing behind them.
