Question: Archie Moses is a small-time thief in Los Angeles who smuggles drugs for drug lord Frank Colton, who launders his drug money through a car dealership. Moses is unaware that his best friend, Rock Keats, is actually LAPD undercover cop Jack Carter, who befriended him only to infiltrate Colton's gang. Carter has Moses include him in Colton's next drug shipment, secretly planning to arrest Colton and take in Moses, whom he has come to care about, unharmed. Carter's undercover status is revealed before he can enact his plan, however, and a hurt Moses pulls a gun on him. During the raid on Colton's warehouse, an out of control crane hits Moses in the back, causing him to accidentally shoot Carter in the head. Moses then flees the state, and is subsequently found and arrested. Carter miraculously survives and makes a full recovery with the aid of his physical therapist, Dr. Traci Flynn, with whom he falls in love. Moses is brought into custody, and he agrees to testify against Colton, but the trial is set to take place at the other side of the country. Carter's superior officer, Capt. Jensen, orders him to personally transfer Moses to the courtroom. Carter harbors resentment against Moses, and tensions escalate once the simple transfer goes awry. Colton learns through bribed federal agents and LAPD officers of Moses' attempt to testify against him. As they flee from Colton's men, Carter and Moses slowly mend their friendship, and are successful in returning to Carter's precinct. However, Colton apparently holds Flynn hostage, and blackmails Carter into turning Moses over in order to save Flynn.

Answer: What is the last name of the person that the undercover cop has come to care about?

Question: The novel tells the story of impoverished, embarrassment-prone Archibald "Archie" Moffam (pronounced "Moom") and his difficult relationship with his art-collecting, hotel-owning, millionaire father-in-law Daniel Brewster, who is the father of Archie's new bride Lucille. Archie's attempts to ingratiate himself with Brewster only get him further into trouble. The story takes place in New York City.Archie Moffam is an Englishman in New York. Like Bertie Wooster he's kind hearted but mentally limited, if not negligible. Unlike Bertie he has no private income. He's a veteran of the First World War. During a stay in New York he bitterly criticises the service at the Cosmopolis Hotel, thus making an enemy of its owner, Daniel Brewster. On a subsequent trip to Miami he meets, falls in love with and marries Brewster's daughter Lucille. Brewster is not delighted. Archie's attempts to make amends by finding employment and by purchasing a valuable objet d'art for Brewster end in disaster. Further indiscretions follow for Archie: he upsets Lucille by apparently paying too much attention to an actress; he bets $1000 on the Giants (then a New York baseball team), but gets into a fight with their star pitcher and injures his arm. He advises Lucille's brother, Bill, who has a habit of getting into relationships with girls of whom his father disapproves, and lends a hand to an old comrade from the war, "The Sausage Chappie", who's lost his memory and forgotten his own name. He upsets Mrs Cora Bates McCall, a vegetarian and healthy food campaigner, by persuading her son to take part in a pie-eating contest. Then there's an incident with a painting which further upsets Brewster. Eventually he pacifies the old curmudgeon by telling him he's about to become a grandfather.

Answer: Who is the Sausage Chappie?
