According to the mafia scenario

In the trunk of a Rolls-Royce with two bullets in the back of his head, Tony Aliso, the owner of a Hollywood film studio and a hardcore gambler, was found. Apparently, he became a victim of a mafia raid. To work out the version of the murder for card debts or machinations, Los Angeles police detective Harry Bosch heads to Las Vegas. During the investigation, it turns out that shortly before the filmmaker's death, he was seen at a poker table with a certain Eleanor Wish - a former FBI agent, a former convict... and Harry's former love of his life. Suddenly, this case becomes very personal for Bosch, and now he has to "keep his cards closer to his chest." Meanwhile, he gains more enemies, not only thugs from Vegas, but also someone from the police department's internal affairs. But when has danger ever stopped Bosch?
