Two young women appeared on the screen — laughing, talking about their travels, and their lives. They looked remarkably alike.

The mother’s heart skipped a beat. Around one girl’s neck was a thin silver necklace with a small letter A, and around the other’s — a necklace with a K.

Exactly the same necklaces she had given her daughters on their tenth birthday.

Her heart started pounding faster. She replayed the video again and again — the same eyes, the same tiny mole under the eye, the same laughter as her girls’. There was no doubt — it was them.
