It gave her pause. Normally, visitors didn’t show up at the door unexpectedly, and they never did this late. Her friends normally knew better to drop in on her unannounced.She glanced at her watch. It was a few minutes past 11:00 p.m. Who was in the hall?An emergency of some sort? She wondered. A problem in the building?She stood and walked to the door. She thought of taking her weapon with her. One could never be too careful in her line of work, but she decided against it, maybe out of pure laziness.She arrived at the door and looked through the peephole. A little wave of relief swept across her. It was her neighbor, Mr. Thomas, the older gentleman she affectionately called “Don Tomás,” the retired diplomat.
