Mark froze in the act of removing his watch, then forced a laugh that sounded like breaking glass. “Pure coincidence. Lots of people have birthmarks.”
“I want you to take a DNA test.”
“Don’t be ridiculous,” he snapped, turning away. “You’re letting your imagination run wild. It’s been a stressful day.”
But his reaction told me everything. The next day, while Mark was at work, I took a few strands of hair from his brush and sent them for testing, along with a swab I took from Sam’s cheek during tooth-brushing time. I told him we were checking for cavities.
The wait was excruciating. Mark grew increasingly distant, spending more time at the office. Meanwhile, Sam and I grew closer.
