In the fifth Matt Riordan novel, Riordan had hoped to leave law forever. But when his ex-girlfriend, attorney Elizabeth Kleinfeldt, reveals her startling conviction that Robert Polhaus, known for abusing women for his own sexual gratification and this history helps convict him of murdering two prostitutes, was unjustly convicted. To find the answer, Riordan must sink into the shadowy scene of sex for sale in order to discover a murderer whose methods are even more sinister than those of Riordan’s new client.
