Eight months pregnant, I practically pushed him out the door for a guys' weekend. Then his best friend called, and the line went dead the second I told him where my husband was.

I knew for three weeks before the dinner party. I poured the wine. I plated the lamb. I let everyone get comfortable. Then I set my fork down.

A midnight walk down an empty country road. A car sunk to its axles in the mud. He went to help. He should have kept walking.

When my marriage cracked, I expected to lean on my oldest friend. I never imagined she was the one holding the knife the whole time.

A late-night notification from a smart speaker app pinged her phone two hundred miles from home. She only opened it out of habit. Then she pressed play.

Her selfie was innocent—until I saw my own bathroom behind her.
