Stephen Jay Schwartz. Beat (2010) 336 pp.
Publishers description: LAPD robbery-homicide detective Hayden Glass has always had trouble controlling his urges. No longer trolling the streets looking for working girls, he has a new obsession—the internet. Infatuated with a woman he finds on a website, Hayden Glasss sex addiction drags him to San Francisco and into a web of corruption and crime. Glasss search for this woman leads him to a massive sex slave trade run by the Russian mafia and protected by a group of powerful and corrupt San Francisco cops. Glass gets co-opted by the FBI to aid in their investigation...but his presence is doing much more harm than good.
Setting: San Francisco; Los Angeles
