Question: Man Overboard! is written in the MacGuffin style which uses what?

full_context: Document 1: Red herring: A red herring is something that misleads or distracts from a relevant or important issue. It may be either a logical fallacy or a literary device that leads readers or audiences towards a false conclusion. A red herring might be intentionally used, such as in mystery fiction or as part of rhetorical strategies (e.g. in politics), or it could be inadvertently used during argumentation.
Document 2: Treasure map: A treasure map is a map that marks the location of buried treasure, a lost mine, a valuable secret or a hidden locale. More common in fiction than in reality, "pirate treasure maps" are often depicted in works of fiction as hand drawn and containing arcane clues for the characters to follow. Regardless of the term's literary use, anything that meets the broad definition of a "map" that describes the location of a "treasure" could appropriately be called a "treasure map."
Document 3: The Crime of Inspector Maigret: The Crime of Inspector Maigret (other English-language titles are Maigret and the Hundred Gibbets and The Hanged Man of Saint-Pholien) is a novel by the Belgian writer Georges Simenon. The original French-language version "Le Pendu de Saint-Pholien" appeared in 1931: it is one of the earliest novels by Simenon featuring the detective Jules Maigret.
Document 4: The Act of Roger Murgatroyd: The Act of Roger Murgatroyd: An Entertainment is a whodunit novel written by Scottish novelist Gilbert Adair first published in 2006. Set in the 1930s and written in the vein of an Agatha Christie novel, it has all the classic ingredients of a 1930s mystery and is, according to the author, "at one and the same time, a celebration, a parody and a critique not only of Agatha Christie but of the whole Golden Age of English whodunits", but also "a whodunit in its own right, so that those readers who were completely uninterested in literary games of the so-called postmodern type could nevertheless settle down comfortably with a good, gripping and intentionally old-fashioned thriller". "The Act of Roger Murgatroyd" is also a locked room mystery.
Document 5: The Floating Dutchman: The Floating Dutchman is a 1952 British crime film directed by Vernon Sewell and starring Dermot Walsh, Sydney Tafler and Mary Germaine. It was known as 'Clue for a Corpse' on U.S. TV. The film was an early product of Merton Park Studios, a British company best known for its Edgar Wallace Mysteries of the 1960s. Its plot involves Dermot Walsh as a Scotland Yard detective who goes undercover amongst jewel thieves after a dead Dutchman is found floating in the river. It is based on a novel by Nicholas Bentley.
Document 6: Quest: A quest serves as a plot device in mythology and fiction: a difficult journey towards a goal, often symbolic or allegorical. Tales of quests figure prominently in the folklore of every nation and ethnic culture. In literature, the object of a quest requires great exertion on the part of the hero, who must overcome many obstacles, typically including much travel. The aspect of travel allows the storyteller to showcase exotic locations and cultures (an objective of the narrative, not of the character). The object of a quest may also have supernatural properties, often leading the protagonist into other worlds and dimensions. The moral of a quest tale often centers on the changed character of the hero.
Document 7: Comedy of intrigue: The comedy of intrigue, also known as the comedy of situation, is a genre of comedy in which dramatic action is prioritised over the development of character, complicated strategems and conspiracies drive the plot, and farcical humour and contrived or ridiculous dramatic situations are often employed. Characterisation tends to be defined only vaguely and the plot gives the illusion of dynamic, constant movement. The German philosopher Hegel argued that characters pursue their aims in such comedies via the use of deception. The genre was first developed in the theatre of classical Rome by Plautus and Terence. Examples of comedies of intrigue include Niccolò Machiavelli's "The Mandrake" (1524), the anonymous Italian play "The Deceived Ones" (1531), Shakespeare's "The Merchant of Venice" (c. 1596) and "Much Ado About Nothing", Thomas Heywood's "The Wise Woman of Hoxton" (c. 1604), Molière's "Scapin the Schemer" (1671), and the plays of Aphra Behn and Thomas D'Urfey.
Document 8: MacGuffin: In fiction, a MacGuffin (sometimes McGuffin or maguffin) is a plot device in the form of some goal, desired object, or other motivator that the protagonist pursues, often with little or no narrative explanation. The MacGuffin's importance to the plot is not the object itself, but rather its effect on the characters and their motivations. The most common type of MacGuffin is a person, place, or thing (such as money or an object of value). Other more abstract types include victory, glory, survival, power, love, or some unexplained driving force.
Document 9: The Third Policeman: The Third Policeman is a novel by Irish writer Brian O'Nolan, writing under the pseudonym Flann O'Brien. It was written between 1939 and 1940, but after it initially failed to find a publisher, the author withdrew the manuscript from circulation and claimed he had lost it. The book remained unpublished at the time of his death in 1966. It was published by MacGibbon & Kee in 1967.
Document 10: The Murchison Murders: The Murchison Murders were a series of three murders, committed by an itinerant stockman named Snowy Rowles, near the rabbit-proof fence in Western Australia during the early 1930s. The case was particularly infamous because Rowles used the murder method that had been suggested by author Arthur Upfield in his then unpublished book "The Sands of Windee", in which he described a way to dispose of a body and thus commit the perfect murder.
Document 11: Murder on the High Seas (book): Murder on the High Seas – "The True Story of the Joe Cool's Tragic Final Voyage" is a true crime book written by Carol Soret Cope, bestselling author of "In the Fast Lane: A True Story of Murder in Miami" and "Stranger Danger: How to Keep Your Child Safe". The book explores the investigation into the mysterious murders aboard the Joe Cool.
Document 12: List of lost mines: Lost mines are a popular form of lost treasure legend. The mine involved is usually of a high-value commodity such as gold, silver or diamonds. Often there is a map (sometimes called a "waybill") purportedly showing the location of the mine. Common reasons given for the mines being lost include:
Document 13: The Hound of the Baskervilles: The Hound of the Baskervilles is the third of the crime novels written by Sir Arthur Conan Doyle featuring the detective Sherlock Holmes. Originally serialised in "The Strand Magazine" from August 1901 to April 1902, it is set largely on Dartmoor in Devon in England's West Country and tells the story of an attempted murder inspired by the legend of a fearsome, diabolical hound of supernatural origin. Sherlock Holmes and his companion Dr. Watson investigate the case. This was the first appearance of Holmes since his apparent death in "The Final Problem", and the success of "The Hound of the Baskervilles" led to the character's eventual revival.
Document 14: List of James Bond gadgets: This is a list of James Bond gadgets featured in the Bond films. The James Bond books and films have featured exotic equipment and vehicles, which often prove to be critically useful. The original books and early adaptations had only relatively minimal pieces like the modified attache case in "From Russia, with Love". However, the gadgets took on a more spectacular profile in the film version of "Goldfinger", and its tremendous success encouraged the following films to have Bond supplied with still more equipment. For instance, it became an expected scene in each film where Q would present and demonstrate Bond's assigned tools for the mission, and it was a near guarantee that each and every piece would be invaluable to Bond in the field. In this sense, Bond gadgets became a prime example of the literary technique of Chekhov's gun.
Document 15: Man Overboard! (Freeman Wills Crofts novel): Man Overboard! (also known as Cold-Blooded Murder) is a detective novel by Freeman Wills Crofts, first published in 1936. It is the fifteenth novel in the Inspector French series. The book is set largely in Northern Ireland, and re-uses two of the characters from the earlier novel "Sir John Magill's Last Journey" (1930) which was set in the same country. As a MacGuffin, the novel centres on a supposedly newly discovered (though possibly fraudulent) reversible chemical process that converts petrol into an inert form which is much safer for transport and storage. The potential commercial value of this discovery leads to intrigue, theft and murder, with everything finally solved by Inspector French after his usual dogged legwork and some flashes of inspiration.
