7. Watch Over Me

Complete story — includes the ending

Navy Commander Darby Wilson, with top secret clearance at the Office of Naval Research, is killed by another motorist, and his assistant Rebecca Ortega is shot to death. The neighbor Bart Roberts says Darby and his wife Katherine always argued, and Rebecca visited regularly. Navy Captain Roger Marcus, concerned about sensitive intelligence, says Wilson was a tech liaison with Axelrod Industries. NCIS Special Agent Meredith Brody learns that Rebecca was involved with Lieutenant Clementine Hill, not Darby. Sebastian finds a biotracker in Darby's corpse that hijacks electronic devices to spy on him. Head of security Oscar Randolph takes Pride to Jason Axelrod and Alexandra Schwartz, who describes their work. Pride finds the other vehicle at Katherine's place; a masked man fires at him before fleeing. She says Darby was meeting Shang Lee, who was also shot dead. As Pride watches over Katherine, the killer tries again. Pride surmises he's after the necklace Darby bought her, which they find has an SD card containing Axelrod's data on a defective hypervelocity missile. They set a trap to find who hired the killer. Meanwhile, Pride tries to fix his wife Linda's Volkswagen Karmann Ghia.
