Passage: In the town of Red Rock, gun salesman Steve Farrell demonstrates the new Colt .45 repeating pistols to the sheriff who is impressed that the United States government just ordered two thousand of these powerful weapons for the army. The demonstration is interrupted when men arrive to transfer one of the prisoners to another jail. As he's being led away, prisoner Jason Brett grabs the pistols, shoots the sheriff, and escapes, pretending that Farrell was his partner. Convinced that Farrell was involved in the escape, the townspeople arrest the innocent gun salesman. In the coming days, Brett initiates a campaign of robberies and cold blooded murder, with regular guns being no match for his Colt .45 pistols.
Four months later, Farrell is released from jail due to a lack of evidence. The new sheriff offers him a letter clearing him of the charges if he reveals Brett's whereabouts. Reasserting his innocence, Farrell vows to go after Brett to retrieve his guns. Farrell tracks his prey into Texas and comes across a band of Indians whom Brett has killed to provide cover for a stagecoach robbery. The only survivor of the attack, Walking Bear, tells Steve about Brett's plan. As the stagecoach approaches, Steve jumps onto the stage from a rock outcropping just in time to fight off the attack by Brett's gang with his own set of Colt .45s. The only passenger on the stage, Beth Donovan, tries to prevent him from fighting off the robbers. 
Question: Who uses the gun salesman?
Jason Brett.

Passage: Following a fire at the Ajuda Palace in 1794, the Prince Regent John VI and his wife Carlotta Joaquina began to use Queluz themselves. The Robillon wing was enlarged and given an upper floor for the use of the princess and her nine children. These additions were destroyed in the fire of 1934. To escape the forces of Napoleon I in 1807, the Portuguese royal family abandoned Queluz and fled to Brazil. The French occupational forces took control of the palace, and their commander, General Junot, made several alterations to the building. On the royal family's return from exile in 1821, the King preferred to live at Mafra, leaving his wife, the Spanish Queen Carlotta Joaquina, to occupy Queluz with her aunt Princess Maria Francisca Benedita. The King visited Queluz infrequently. It was on one of these rare visits that João VI died in the circular domed King's Bedroom in 1826.Carlotta Joaquina, sometimes described as sinister, is said to have been ambitious and violent. Her features were reportedly ugly, and she was short in stature. Whatever her shortcomings she lived in great style at Queluz, employing an orchestra which William Beckford described as the finest in Europe. The Queen also had a small private theatre in the gardens, of which nothing remains today. She died at the palace in 1830.Following the death of Carlotta Joaquina, Queluz saw only intermittent use as a royal residence and was not again the primary residence of Portuguese royalty. Carlotta Joaquina's son King Miguel used the palace during the three-year civil war which he fought against his brother King Pedro IV, before being forced by his brother in 1834 to abdicate and go into exile. A year later, Pedro IV died of tuberculosis at the age of 35 at Queluz, the palace of his birth. Pedro I's daughter Maria II ruled until her death in 1853 and was succeeded by her son Pedro V. Following his untimely death in the cholera epidemic of 1861, the throne passed to his brother Luís. From this time the royal family lived chiefly at the rebuilt Ajuda Palace in Lisbon. On the assassination of Luís' son Carlos I in 1908, the palace passed into the ownership of the state. Portugal was in the turmoil of revolution and the monarchy fell two years later. 
Question: What are the full names of the people who died at the palace?
Carlotta Joaquina.

Passage: Will Graham is a former FBI criminal profiler who has retired because of a mental breakdown after being attacked by a cannibalistic serial killer, Dr. Hannibal Lecktor, whom he captured. Graham is approached at his Florida home by his former FBI superior Jack Crawford, who is seeking help with a new serial killer case. Promising his wife that he will do nothing more than examine evidence and not risk physical harm, Graham agrees to visit the most recent crime scene in Atlanta, where he tries to enter the mindset of the killer, now dubbed the "Tooth Fairy" by the police for the bite marks left on his victims.
Having found the killer's fingerprints, Graham meets with Crawford. They are accosted by tabloid journalist Freddy Lounds, with whom Graham has a bitter history; Lounds' paper had run photographs of Graham taken secretly while he was hospitalized. Graham pays a visit to Lecktor, a former psychiatrist, in his cell and asks for his insight into the killer's motivations. After a tense conversation, Lecktor agrees to look at the case file. Later, Lecktor manages to obtain Graham's home address by deceit while ostensibly making a phone call to his attorney.
Graham travels to the first crime scene in Birmingham, Alabama, where he is contacted by Crawford, who tells him of Lounds' tabloid story on the case. Crawford also patches Graham through to Frederick Chilton, Lecktor's warden, who has found a note in Lecktor's personal effects. Reading it, they realize it is from the Tooth Fairy, expressing admiration for Lecktor—and an interest in Graham. Crawford brings Graham to the FBI Academy at Quantico, where a missing section of the note is analyzed to determine what Lecktor has removed. It is found to be an instruction to communicate through the personals section of the National Tattler, Lounds' newspaper. 
Question: What is the last name of the person that the profiler asks for advice in the new serial killer case?

Lecktor.
