Perfect for you if...

You love legal thrillers with real courtroom tension and a lawyer protagonist who has skin in the game.
You enjoy stories where the obvious suspect turns out to be something far more complicated than it appears.
You want a page-turner that doesn't rely on gimmicks, just solid plotting and high stakes.

Maybe not for you if...

You prefer fast-paced crime procedurals told from the detective's point of view rather than the defence table.
You're put off by stories involving violence against children, even when handled with restraint.
You want a standalone thriller; this is the first in Dugoni's Donley series and builds ongoing character arcs.

About this book

In San Francisco's Tenderloin district, a teenage street hustler is murdered at a boys' shelter. The priest who runs the facility is accused of the crime, despite his claims of innocence. Attorney Peter Donley, who has spent three years working at his uncle's small law firm, takes on the case. As Donley prepares to leave for a more lucrative position, he must put his plans aside to defend Father Thomas Martin in court. He faces opposition from a district attorney focused on generating publicity and a homicide detective seeking revenge. While investigating the case, Donley uncovers secrets connected to the murder and risks his career to save his client and reveal the truth.
