Luca Brasi is Mafia boss Vito Corleone's personal enforcer. His intense brutality unnerves Vito Corleone. In one two-week killing spree, he murders six men who had attempted to assassinate Don Corleone, continuing his ferocious rampage until Vito called a halt to it, ending the "Olive Oil War." Brasi's loyalty to Don Corleone is unquestioned, and he is said to have killed a Corleone soldier for making the Corleone family look bad. Brasi says he would sooner kill himself than betray the Godfather. In one early incident Brasi kills two of Al Capone's henchmen who were hired to assassinate Don Corleone. Brasi subdued both men, binding and then gagging them with towels. As Brasi dismembered one with an axe, the other terrified man choked to death on the towel. Later in the novel, an old Sicilian woman, a former midwife, tells Vito's youngest son, Michael, that years earlier Brasi murdered an Irishprostitute hours after she gave birth to his child. He then forced the midwife to put the live infant into a burning furnace. The distraught woman sought Vito Corleone's help. Don Corleone intervened, protecting the woman while covering up Brasi's crime and gaining his undying service and loyalty. Brasi was surprised to be invited to Connie Corleone's wedding, though Vito included him reluctantly, doing so only as a professional courtesy. To express his respect and gratitude, Brasi personally presents the Don a large cash gift for his daughter's bridal purse, purportedly the largest sum given. During the reception, Michael's girlfriend, Kay Adams, asks Michael about Brasi. He explains that his father once helped his godson Johnny Fontane's singing career with Brasi's assistance. Don Corleone had offered bandleader Les Halley $10,000 to release Fontane from a personal service contract that unfairly exploited Fontane's rising fame. When Halley refused, Don Corleone returned the next day with Luca Brasi to make Halley, "an offer he couldn't refuse." In the novel, Vito, accompanied by Brasi and Consigliere Genco Abbandando, holds Halley at gunpoint after initially offering the bandleader $20,000, telling him that either his signature or his brains would be on the contract. The Don then pays $10,000 after forcing Halley to sign the release. In the film, Michael explains to Kay, Halley signed a release for only $1,000. To draw out rival mobster Virgil Sollozzo, Don Corleone orders Brasi to feign dissatisfaction working for the Corleones and desires to switch allegiances. Don Tattaglia, hearing this, arranges a meeting between Brasi and Sollozzo. Brasi arrives, wearing a bulletproof vest. Sollozzo, unfooled by the ruse, has him killed, then sends the vest stuffed with dead fish to the Corleones, an old Sicilian message saying that Brasi, "sleeps with the fishes." Brasi's role as personal enforcer/bodyguard to the Don is later filled by Al Neri. Following Neri's initiation, Vito tells Michael that now he has his "Luca".
