She is an ordinary office worker barely surviving on rent money and attendance bonuses—until the night her neighbor is murdered and a rat tells her what it saw.
Soon, she discovers that every pest in the city can speak to her. Flies remember whose blood was at the crime scene. Mosquitoes know where a suspect has been. Cockroaches crawl through locked rooms and overhear secrets no human witness could survive to tell.
Her impossible tips quickly make her the police unit’s secret weapon, helping solve cases everyone else has given up on. But the deeper she follows her tiny informants into the city’s darkest corners, the more dangerous the truth becomes.
Then the pests uncover evidence linked to a killer who leaves no witnesses behind. And when he realizes someone can see inside every room he enters, the hunt suddenly turns toward her.
