Undercover Vice and Narcotics Detective Cade Taylor knows the sultry streets and complex underground of Miami better than he knows himself, and definitely better than anyone knows him. But when the underground bursts into the forefront of Cade's life with the inexplicable murders of his informants known as The Four Horsemen, Cade must resort to his knowledge of the crime world to keep alive.

Driven to emotional exile by his divorce and the secretive VIN unit he excels in, Cade isn't accustomed to being the center of attention. Leading a "normal" life isn't in the cards for him he spends as much time at the Medical Examiner's office as he does relishing the decadence and glamour of the city. Secretly investigating if he's being set up as a murderer or if he's next on the hit list, Cade races against the clock through Miami, while trying to protect the confidential secrets of the clandestine drug world he lives in--not an easy feat when keeping his own secrets.

Digging deep into the crime world he spends his life disassembling from the inside, Cade finds that the dark streets of Miami hide more than money laundering, drug trafficking, and double lives--and that the answers he needs don't always shine in the sunlight.
