[Q]: What is the alias of the undercover agent?  Answer the above question based on the context below:  Arthur "Cody" Jarrett is a ruthless, psychotic criminal and leader of the Jarrett gang. Although married to Verna, he is overly attached to his equally crooked and determined mother, "Ma" Jarrett, his only true confidant. Cody and his gang rob a mail train in the Sierra Nevada mountains (referred to as "the tunnel job"), killing four members of the train's crew. While on the lam, Cody has a severe, instant migraine, which Ma nurses him through. Afterward, Ma and Cody have a quick drink and toast, "Top of the world!" before rejoining the others. The gang uses the cover of a storm to change hideouts and split up.  Informants enable the authorities close in on a motor court in Los Angeles where Cody, Verna, and Ma are holed up. Cody shoots and wounds US Treasury investigator Philip Evans and makes his escape. He then puts his emergency scheme in motion: confess to a lesser crime (the "hotel job") committed by an associate in Springfield, Illinois at the same time as the tunnel job - which was federal crime - thus providing him with a false alibi and assuring him a lesser sentence. He flies to Illinois and turns himself in, where he receives one- to three-years in state prison. This ruse does not fool Evans, however, who plants undercover agent Hank Fallon (aka prisoner Vic Pardo) in Cody's cell in the Illinois State Penitentiary. His task is to find the "Trader", a fence who launders stolen money for Cody. Hank's angle is to become a surrogate "ma" to Cody and get him to talk.

[Q]: What is the name of the album that loses some of the mathematical-like rhythmical quick changes of past releases and uses "angular" riffs, mid-tempo and common 4/4 beats?  Answer the above question based on the context below:  With 2008's obZen, Meshuggah moved away from the experimentation of 2002's Nothing and 2005's Catch Thirtythree to return to the musical style of its previous albums, such as Contradictions Collapse, Destroy Erase Improve and Chaosphere, while still maintaining its focus on musical and technical innovation. The album loses some of the mathematical-like rhythmal quick changes of past releases and the melodic orchestration of Catch Thirty-Three and uses "angular" riffs, mid-tempo and common 4/4 beats. The album is a culmination of the band's previous work. Meshuggah decided to self-produce because it sought to retain artistic control over the recording and mixing process.For obZen, Haake returned to the drum kit most notably with his performance on the song "Bleed". In an interview for Gravemusic.com, Haake stated, "['Bleed'] was a big effort for me to learn, I had to find a totally new approach to playing the double bass drums to be able to do that stuff. I had never really done anything like that before like the fast bursts that go all the way through the song basically. So I actually spent as much time practicing that track alone as I did with all of the other tracks combined. It's kind of a big feat to change your approach like that and I'm glad we were able to nail it for the album. For a while though we didn't even know if it was going to make it to the album." Hagström also stated, "obZen is one of the most highly technical offerings the band has ever put to tape". Revolver Magazine confirms this statement: "At first listen, obZen seems less challenging to the listener than some of the band's other records, and most of the songs flow smoothly from one syncopated passage to the next. However, careful examination reveals that the material is some of the group's most complicated".

[Q]: What is the last name of the person whose preliminary work came to a halt in April 1948?  Answer the above question based on the context below:  In 1947, Walton was presented with the Royal Philharmonic Society's Gold Medal. In the same year he accepted an invitation from the BBC to compose his first opera. He decided to base it on Chaucer's Troilus and Criseyde, but his preliminary work came to a halt in April 1948 when Alice Wimborne died. To take Walton's mind off his grief, the music publisher Leslie Boosey persuaded him to be a British delegate to a conference on copyright in Buenos Aires later that year.  While there, Walton met Susana Gil Passo (1926–2010), daughter of an Argentine lawyer. At 22 she was 24 years younger than Walton (Alice Wimborne had been 22 years his senior), and at first she ridiculed his romantic interest in her. He persisted, and she eventually accepted his proposal of marriage. The wedding was held in Buenos Aires in December 1948. From the start of their marriage, the couple spent half the year on the Italian island of Ischia, and by the mid-1950s they lived there permanently.Walton's last work of the 1940s was his music for Olivier's film of Hamlet (1948). After that, he focused his attentions on his opera Troilus and Cressida. On the advice of the BBC, he invited Christopher Hassall to write the libretto. This did not help Walton's relations with the Sitwells, each of whom thought he or she should have been asked to be his librettist. Work continued slowly over the next few years, with many breaks while Walton turned to other things. In 1950 he and Heifetz recorded the Violin Concerto for EMI. In 1951 Walton was knighted. In the same year, he prepared an authorised version of Façade, which had undergone many revisions since its premiere. In 1953, following the accession of Elizabeth II he was again called on to write a coronation march, Orb and Sceptre; he was also commissioned to write a choral setting of the Te Deum for the occasion.Troilus and Cressida was presented at Covent Garden on 3 December 1954. Its preparation was dogged by misfortunes. Olivier, originally scheduled to direct it, backed out, as did Henry...
