You've been running the same hotel for thirty years. You photograph every guest, count every face, record every detail with the precision of someone who trusts numbers more than people. The routine has never failed you.

Until Saturday morning, when your breakfast count comes up wrong.

Ten guests checked in. Ten rooms occupied. Ten signatures in the registry. But eleven people sit on your terrace, and when you try to explain the impossible mathematics, no one believes you. Not your daughter. Not the other guests. Not even yourself, until you start looking closer at the faces you've been counting.

Some guests are exactly who they claim to be. Others are performing themselves so carefully that only a woman who's spent thirty years cataloguing strangers would notice the seams. And when your perfect count reveals someone who's learned to be in three places at once, you realize that the most dangerous mysteries hide in plain sight—at breakfast tables, in signed registries, in photographs that show exactly what happened and nothing about what it means.

Trust the numbers. The numbers never lie. But the people behind them? They're more complicated than any count can capture.
