Execution Dock

London's Victorian Thames is a world of staggering contrasts — merchant ships laden with imperial wealth gliding past riverbanks where the city's most vulnerable are bought and sold. When the body of a young boy is pulled from the water, Commander William Monk of the River Police sets his sights on the man responsible: a ruthless operator who has turned exploitation into an empire. But securing justice means navigating a legal system that can be bent by money and influence, and Monk soon discovers that doing what is right and doing what is lawful are not always the same thing. The emotional stakes here are raw and unrelenting.

What distinguishes Perry's writing in this installment is her refusal to keep the darkness at arm's length. She renders the Thames-side underworld with physical immediacy — the smell of the river, the press of bodies, the moral rot beneath the commerce — while never losing sight of the human cost. The novel's pacing is deliberate in the best sense, allowing moral complexity to accumulate rather than simply delivering plot twists. Readers who have followed Monk across sixteen books will find his convictions tested in ways that feel genuinely hard-won.
