Blood Work

Terry McCaleb, a retired FBI profiler who once led investigations into notorious serial killers, including one known as the Code Killer, lives aboard a fishing boat called The Following Sea in a San Pedro marina. He is recovering from a heart transplant necessitated by cardiomyopathy, a stress-induced weakening of the heart muscle that ended his career. One morning, Graciela Rivers boards his boat uninvited, having tracked him through a recent newspaper profile. She asks him to investigate the unsolved murder of her sister, Gloria Torres, who was shot during an apparent robbery at a convenience store in Canoga Park. McCaleb tries to turn her away, but Graciela reveals the connection that changes everything: Gloria was his organ donor. McCaleb received Gloria's heart.

The revelation unsettles McCaleb deeply. He had assumed his donor died in an accident. A murder attaches what he calls "evil intent" to his survival. His cardiologist and surgeon, Dr. Bonnie Fox, strongly opposes any involvement, warning that the stress could trigger organ rejection. Despite her objections, McCaleb agrees to take the case, driven by an inescapable debt to the woman whose heart keeps him alive.

McCaleb visits LAPD's West Valley Division to meet the detectives assigned to the case, Eddie Arrango and Dennis Walters. Arrango is hostile and territorial but shows McCaleb the store's surveillance tape: a masked gunman enters the Sherman Market, grabs Gloria from behind, shoots her in the head, then kills the store owner, Chan Ho Kang, collects his bullet casings, and exits. Shortly after, an unidentified man wraps Gloria's head wound, calls 911 from a pay phone, and disappears. McCaleb observes that the shooter's methodical behavior indicates prior experience. Arrango's reaction confirms a link to another case, but the lieutenant denies McCaleb access to the files.

Through a newspaper database search, McCaleb connects the Torres case to the ATM shooting death of James Cordell in Lancaster. The lead detective, Jaye Winston of the Sheriff's Department, confirms that ballistics link the cases; the same rounds were fired from the same Heckler & Koch P7, an expensive compact pistol unusual in street crimes. She provides McCaleb with both case files and explains her theory: the shooter is a career criminal facing California's three-strikes law, which mandates life imprisonment upon a third felony conviction, who kills witnesses to avoid capture.

Unable to drive because his sternum is still healing, McCaleb hires his marina neighbor Buddy Lockridge as his driver. He pursues a promising suspect, Mikail Bolotov, a Russian émigré with two prior robbery convictions who lives near the crime scenes, but a subsequent hypnosis session with the Cordell scene witness, James Noone, eliminates Bolotov by establishing the driver had no neck tattoo, a feature Bolotov conspicuously possesses. Meanwhile, McCaleb builds a relationship with Graciela and with Gloria's seven-year-old son, Raymond, who is now in Graciela's care. Their growing bond deepens McCaleb's resolve.

A breakthrough comes when McCaleb re-reviews the surveillance video. He discovers that Gloria was wearing four earrings, including a dangling cross, but only three were recovered. Graciela confirms the cross was Gloria's daily signature, fastened with a safety hasp unlikely to fall off. More startling, the Good Samaritan's 911 call was logged 34 seconds before the shooting occurred according to the store's video clock. McCaleb concludes the killer took the earring as a trophy, transforming the case from a random robbery into a targeted killing with a pathological motive. He presents his findings to Winston, arguing the shooter derives power from killing on camera and collecting personal trophies. A visit to the Cordell family confirms that a photograph was also taken from Cordell's vehicle.

The case expands when an FBI ballistics analysis links the Torres and Cordell bullets to a fragment from the skull of Donald Kenyon, a convicted embezzler assassinated in his Beverly Hills home. The killer's words on the FBI's surveillance tape, "Don't forget the cannoli" (281), a quote from The Godfather, match the lip movements on both the Cordell and Torres tapes, confirming all three murders were committed by the same person.

McCaleb makes the critical breakthrough connecting all three victims through their blood. At the newspaper plant where Gloria worked, he notices a blood drive poster and recalls a commendation in Cordell's files for chairing his company's blood drive. Accessing the computer system of BOPRA (Blood and Organ Procurement and Request Agency), the regional organ procurement agency, he and Graciela find all three victims listed as rare type AB/CMV-negative blood and organ donors. McCaleb concludes that someone used the donor list to identify and kill potential organ donors, refining the method each time until, with Torres, the shooter called 911 before the shooting to ensure the organs were successfully recovered.

McCaleb becomes the primary suspect when FBI agents execute a search warrant on his boat, finding planted evidence: a baseball cap matching Noone's hypnosis description and a bag containing trophies from all three victims. His ownership of a black Grand Cherokee and his direct benefit from Gloria's death provide apparent motive. However, Lockridge has already found and removed the murder weapon from a diving bag tied under the hull.

With Winston's secret help, McCaleb identifies the shooter by rewatching the hypnosis tape and noticing that Noone displayed awareness inconsistent with a genuine trance. A video technician confirms the Good Samaritan and Noone are the same person. At Noone's address in North Hollywood, McCaleb finds a warehouse containing surveillance files on all three victims and a computer message addressed to him. The password, 903472568, is the Code Killer's signature number, using every digit except "1" to encode "no one." The message reveals Noone is the Code Killer, the serial murderer McCaleb hunted for years without success. The killer engineered Gloria's death to give McCaleb a new heart: "I chose her for you. She was my Valentine to you" (417).

Fingerprints yield a match to Daniel Crimmins, a 32-year-old LAPD Academy washout whose hacking skills gave him access to the BOPRA database. McCaleb tells Graciela the truth, and she asks him to leave. Using details from the hypnosis session, McCaleb tracks Crimmins to Playa Grande on the Baja coast, where Crimmins has anticipated his arrival, stealing McCaleb's gun and taking Graciela and Raymond hostage.

McCaleb confronts Crimmins on the beach. Crimmins holds the stolen gun and demands to be released. McCaleb produces the HK P7 that Lockridge recovered. Crimmins pulls the trigger, but the hammer snaps on an empty chamber because McCaleb never chambers a round. McCaleb fires, killing Crimmins. "I saved you. I gave you life," Crimmins says with his last breath (456). McCaleb responds, "You're wrong. I traded you for me. I saved myself" (456). He stages the scene as a suicide, then searches the bluff above the village and finds Graciela and Raymond imprisoned in an underground septic tank, frightened but unharmed.

Back in the United States, Winston visits McCaleb to report that Crimmins's body was found with a typed suicide note. She quietly notes his Cherokee is covered in dust, a tacit acknowledgment of her suspicion. McCaleb says he will get it washed. In the final scene, McCaleb pilots The Following Sea toward Catalina Island with Graciela and Raymond aboard. The trip is a test, Graciela's word, to determine whether they can build a life together despite the painful knowledge of why McCaleb is alive. He accepts this as enough, feeling purpose and something close to faith for the first time in years, as the island rises on the horizon.
