Matt Sorenson (Dolph Lundgren), a former boxer and San Francisco cop, now makes a living collecting debts for small businesses. The brutal death of his high-powered younger brother, Michael, changes all that forever. Intent on finding his brother's killer, Sorenson infiltrates the powerful inner world of politics, business intrigue and casual sex. Rejecting the police and media theory that the murder is the work of a female prostitute, Sorensen's focus falls on the corrupt big city businessman, Jim Conway. His obsession to discover the killer's identity mounts as a series of other men are found murdered in a similar fashion. Sorenson loses all objectivity and becomes a vigilante.
The novel had been described by the Today programme as 'harrowing, but [its] grim, poetic vision makes it the best novel of its kind for years'. The Sunday Times said that 'violent and vicious, Lindsay's unsparing tale beds down with the imagination like a succubus'. Daily Express called it 'tautly and skillfully written - a genuine, can't-put-it-down, turn-off-the-telly-read'.
