The famous Cabrillo Marina is home to the Following Sea, McCaleb's father's boat and business and then McCaleb's boat and home. It is also home to Buddy Lockridge's home boat.
Cabrillo is central to the plot as many events take place there : the first encounter with Graciela Rivers, the day with Graciela and Raymond, the killer's intrusion, Walters and Arrango's boat search etc.
It serves as an ideal lair for the charismatic McCaleb, for he is usually calm and relaxed, quite like this lazy holiday harbor, but is capable of vengeful fury just like the waves that gently rock the Following Sea.
The fact that McCaleb always finds help there, thanks to Lockridge, confirms Cabrillo as the nurturing home.
Chatsworth, a rich northern Los Angeles suburb, houses one of the killer's victims, James Cordell. McCaleb makes multiple visits to Cordell's widow hoping to advance his investigations, but it is in fact Buddy Lockridge who makes a noteworthy discovery in Chatsworth : the dustless rectangular spot left on the SUV's dashboard by the family photo the killer took. This breakthrough confirms that the killer collected "souvenirs" from his victims.
Cedars Sinai hospital, where Terry spent two years waiting for a heart transplant, is a renowned hospital specializing in cardiology among other fields. Dr Bonnie Fox, Terry's cardiologist and a Cedars Sinai doctor, provided him with the list of blood type AB organ donors from BOPRA's database after a tense meeting held in her office at Cedars Sinai. This particular information pushed McCaleb's work light years in the right direction.
