Every day without fail, Travis Devine puts on a cheap suit, grabs his faux-leather briefcase, and boards the 6:20 commuter train to Manhattan, where he works as an entry-level analyst at the city’s most prestigious investment firm. In the mornings, he gazes out the train window at the lavish homes of the uberwealthy, dreaming about joining their ranks. In the evenings, he listens to the fiscal news on his phone, already preparing for the next grueling day in the cutthroat realm of finance. Then one morning Devine’s tedious routine is shattered by an anonymous email: She is dead. 

Michael Campion was a people's hero, a popular governor's son who publicly battled against a rare and debilitating heart illness. When he vanished without a trace one evening, his disappearance and the search to find him, dead or alive, hit the headlines daily. But the trail went cold very quickly. Now with a new lead, Detective Lindsay Boxer is determined to find out what happened to San Francisco's Golden Boy.

Behind the closed doors of San Fransisco's grandest mansions, beautiful people party the nights away in a heady mix of money, drugs, drink, and sex. But the rich and famous aren't the only ones with the keys to these most exclusive of addresses; someone else is intent on crashing the party. A rock star, a fashion designer, a software tycoon, and a millionaire heiress: Each is glamorous, stunningly attractive and incredibly rich, but their similarities don't end there. They have something else in common too. They are all dead.

When two dead bodies are found inside a wrecked car on the Golden Gate Bridge, Detective Lindsay Boxer doubts that it will be anything as simple as a traffic accident. The scene is more gruesome than anything she has seen before. It definitely wasn’t the crash that killed these people. While Lindsay starts to piece this case together, she gets a call she wasn’t expecting. Sightings of her ex-colleague-turned-ruthless-killer Mackie Morales have been reported.

Detective Lindsay Boxer has everything she could possibly want. Her marriage and baby daughter are perfect, and life in Homicide in the San Francisco Police Department is going well. But all that could change in an instant. Lindsay is called to a crime scene at the Four Seasons Hotel. There is a dead man in one of the rooms, shot at close range. The man checked in under a false name with no ID on him, so the first puzzle will be finding out who he is.
