In a remote Alpine monastery where silence is sacred and secrets are currency, a powerful Cardinal dies during a ritual feast-after drinking from the same glass as five others.
Only one man dies.
No poison is found.
And the truth should be impossible.
Sister Beatrice possesses a rare and unsettling gift-she can read the world through scent. Every lie, every fear, every hidden sin leaves a trace in the air. But this time, the trail leads to something far more dangerous than murder.
A perfectly engineered death.
As Beatrice unravels a conspiracy hidden within sacred rituals, she discovers a chilling reality: the killer didn't poison the wine-they poisoned the man days before, using a deadly combination of chemistry, faith, and manipulation.
