My first posting was Fort Huachuca, Arizona, the Army’s intelligence schoolhouse. I spent two years in the military intelligence captain’s career course pipeline, learning tradecraft, building analytical frameworks, earning my place among peers who were just as sharp and just as driven.

The desert was brutal and beautiful. I ran five miles every morning before the sun turned the air into a furnace. I called home once a week. My mother always asked when I was coming to visit. My father always asked if I was eating enough.

Amanda rarely came up in conversation, and when she did it was through my mother. Amanda’s seeing someone new, or Amanda got a promotion at the real estate office.

I was promoted to first lieutenant in 2014. I called home to tell my parents. My mother said, “That’s wonderful, honey.” My father said, “Keep climbing.”

I tried Amanda’s number. She didn’t pick up. I left a message. She never returned it.
