Tropical Depression (Billy Knight Thrillers 1)

When a hostage situation turns deadly, Billy Knight loses everything—his wife, his daughter, and his career in law enforcement. Devastated, he heads to Key West to put down his gun and pick up a rod and reel as a fishing boat captain. But former co-worker Roscoe McAuley isn’t ready to let Billy rest.
 
When Roscoe tells Billy that his son was the victim of premeditated murder during the riots following the Rodney King trial, Billy sends him away. When Roscoe himself turns up dead a few weeks later, however, Billy can’t keep from getting sucked back into Los Angeles, and the streets that took so much from him.
 
Billy’s investigations into the death of a former cop, and his son, will take him up to the highest echelons of the LAPD, finding corruption at every level. It puts him on a collision course with the law, with his past, with his former fellow officers, and with the dark aftermath of the civil rights movement—in a case with more dangerous blind curves than Mulholland Drive.
