Behind them, a woman in a charcoal suit carrying a black folder with the hospital seal. Vivian’s smile cracked. “Marcus, thank God, this nurse is interfering with—” He didn’t even look at her. He looked at me. “Dr. Vega. Your assessment.” The room went silent.

At the small silver pin on my collar she’d mistaken for decoration. Her voice came out like paper. “You… you were undercover?” I picked up the correct syringe, saved the patient in ninety seconds, then finally turned to her. “No. I was just doing my job. You were the one pretending.”
